Display part number 6ES ES SIMATIC PCS7, Batch and Options SIMATIC PCS7 SW-Packages (BLE, ES, OS) Description: In PCS 7, the data/messages of an AS block (function block, FB) are displayed by default in a faceplate. The case might arise, however, that the data/messages of other AS blocks are to be displayed in a faceplate. This entry describes how to display messages of an additional block in your PCS 7 faceplate. Sample application: A technological function, e.g. motor with current display, is to be realized with several blocks. ( 填写文档类型 : 常问问题 ) P6-13

7 Fig. 01 The "MOT" block (block type "MOTOR", FB66) is used to control a motor. In addition, the motor current is to be displayed and monitored with the "MOT_IMEAS" block (block type "MEAS_MON", FB65). When the current value exceeds a specific limit, an alarm is supposed to be triggered. The "Limit value monitoring" function of the "MOT_IMEAS" block is used for this. The data of the "MOT_IMEAS" block is not displayed by default in the faceplate of the "MOT" block of the motor. The aim is to display the data of the "MOT_IMEAS" block (motor current, current monitoring limits, alarms and messages) in the faceplate of the "MOT" block of the motor. Notes: This entry describes different ways of how the messages of the additional AS block "MOT_IMEAS" can be displayed in the "Message" view of the OS faceplate "MOT". Therefore, we are only dealing with the "Alarm" view of a faceplate. PCS 7 faceplates use the WinCC Alarm Control in the "Alarm" view to display the messages of a block. When you open the "Message" view of a block, the message filter is set by default so that only the block-relevant messages are displayed. Entry ID describes how you can also have the other views of an OS faceplate supplied with the data of additional AS blocks. The various solutions are not exclusively for the "MOTOR" or "MEAS_MON" block type and you can use them also for other block types. This entry also gives instructions on how to configure and display the group display. No. Procedure 1 Use the free alarm signal of the "original" block In this solution the signal for limit value monitoring of the motor current is formed in the CFC. How this signal is formed is not dealt with here. This signal could be interconnected with an alarm signal of the "MOTOR" block. The actual current value could also be interconnected as a message-associated value. Check whether the block to be extended ("MOTOR" FB66) has freely available message signals. However, the "MOTOR" (FB66) block does not have any input signal with which an additional (user-defined) message can be triggered. Therefore, this solution cannot be used in this special case. ( 填写文档类型 : 常问问题 ) P7-13

8 When you create your own blocks, you should make sure that you interconnect unused message signals of "ALARM_8P" blocks with the interface of the block. In this way, you can later configure additional messages with a minimum of effort. Entry ID describes this principle. Additional configuration steps for the group display Check and if necessary, extend the group display of the block icon The group display of the block icon is used both for displaying the messages of your own AS block and also for displaying the messages of the additional AS block. Make sure that the group display can display the messages of all the message classes used. If the group display of the block icon of the "MOTOR" block were to be used to display the messages of the "MEAS_MON", the group display would have to be extended. The group display of the "MOTOR" block displays by default only messages of the types "AS Process Control Error" and "AS Process Control Fault". The group display would have to be extended to be able to display message types for limit value monitoring (e.g. "Alarm High", "Warning High" ). 2 Trigger message through the additional block and change the user text block "Origin" In this solution, the message for limit violation of the motor current is triggered by the "MOT_IMEAS" ("MEAS_MON") block. In the "PCS7 Message Configuration" dialog, change the "Origin" field (user text block of a message) accordingly. For this, in the "Origin" field you replace the character string "$$AKZ$$" with the complete measuring point designation of the "MOT" block. Fig. 02 Note: It might be that the message text for the origin cannot be changed in the CFC, because there is no release. Proceed as follows to release change of the "Origin" in the CFC. Open the "PCS7 Message Configuration" dialog of the block from the block folder of the Component View of the SIMATIC Manager. Remove the lock. At this point, do not yet change the actual text for the "Origin". Fig ( 填写文档类型 : 常问问题 ) P8-13

9 Update the Block Type to make the change effective. Additional configuration steps for the group display When compiling the OS, a tag is created for each alarm-compatible block in the Tag Management of the OS, which contains the group value of all the alarm blocks included (ALARM_8P, NOTIFY_8P). A group tag, "*.EventState", is created for the "MOT" block and the additional block "MOT_IMEAS". Both group tags must be interconnected with a group display in the process picture so that the messages are displayed in the group displays of the overview area and the navigation window. The "Create/Update block icons" function incorporates the block icons with the interconnected group displays automatically in the process picture. Interconnect group display of the additional block in the picture The group value of the additional block (tag "*.EventState" of the "MOT_IMEAS" block) must be interconnected with a group display in the process picture so that the current monitoring messages are displayed in the group displays of the overview area and the navigation window. This is achieved usually by incorporating the faceplate of the additional block "MOT_IMEAS" in the picture ("Create/Update block icons" function). If you do not need the block icon for displaying the motor current ("MEAS_MON") in the process picture, then you should not just simply delete this icon, because this would make the configuration of the group hierarchy incomplete. In this case you can set the "Visible" property of the block to "no". Check and if necessary, extend the group display of the block icon If the block icon for the display of the current ("MEAS_MON") is not visible in the process picture, you should configure a group display for displaying the current monitoring in the process picture. For this, you can add another group display for displaying the current monitoring to the block icon of the "MOT" block (block type "MOTOR"). This group display must be interconnected with the group value of the "MOT_IMEAS" block. 3 Trigger message by the additional block and set the property "MULTI_INSTANCE" to "yes" in the faceplate Warning! It is absolutely necessary to observe the restrictions at the end of this proposed solution. In the Graphics Designer you can set the "MULTI_INSTANCE" property to "yes" in a faceplate in order to display the data of multiple AS blocks in one OS faceplate. The property "MULTI_INSTANCE" has the default value "no". The "MULTI_INSTANCE" property of the object "@Faceplate" is located in the template picture "@pg_motor.pdl" of the faceplate in the property group "Miscellaneous". Fig. 04 When you open the "Alarm" view of a block, the message filter in the Alarm Control is set according to the property "MULTI_INSTANCE": "MULTI_INSTANCE = no" Only those messages are displayed whose origin exactly matches the measuring point ( 填写文档类型 : 常问问题 ) P9-13

10 designation of the faceplate. This means that only the messages of the "MOT" block are displayed in the Alarm Control. The messages of the additional block "MOT_IMEAS" are not displayed in the Alarm Control. "MULTI_INSTANCE = yes" The text of the measuring point designation is prepared for further processing in that the end of the measuring point designation, the name of the AS block, is truncated. This modified measuring point designation is then used as a filter criterion. Only those messages are displayed whose origin begins with the text of the modified measuring point designation. This means that in addition to the messages of the "MOT" block, also the messages of other blocks, e.g. "MOT_IMEAS", are displayed in the Alarm Control. Restrictions If you change the "MULTI_INSTANCE" option of an existing faceplate to "yes", then you must change the complete faceplate. All the dynamizations in all the template pictures (tag interconnections, scripts) must be checked and if necessary changed, because the modified measuring point designation (measuring point designation without the block names) applies. Therefore, this proposed solution is possible in principle, but is very complicated and prone to errors. o The existing block must be completely revised. Here, the function of the whole block must be completely analyzed and changed. The changed block must be completely tested. o The PCS 7 standard blocks are fully documented with regard to their use. However, the blocks are not fully documented with regard to internal function and programming. Users have the option of determining the internal function themselves. This involves a great deal of time. o The error probability is relatively high. General information on the topic of "Configuring multi-instances" is available in the manual "PCS 7 - Programming Instructions for Blocks". Changes in the template pictures or standard functions might be lost when the OS project editor is run or the software updated (installation of a new version of WinCC, a service pack or a hotfix). Only for PCS 7 V7.0 SP1 In PCS 7 V7.0 SP1, only the messages of the original block are display despite using the "MULTI_INSTANCE=yes" option. Entry ID provides are remedy. Additional configuration steps for the group display The same applies here for configuration of the group display as described in Point 2. 4 Trigger message by the additional block and change the script for setting the message filter By default, PCS 7 faceplates use the picture "pcs7_alarm.pdl" for displaying the messages. When you open this picture, among other things the filter for displaying the messages is set. You can change the script for setting the message filter so that the messages of other blocks are also displayed. The following figure shows the changed section of the script that is executed when the "Message" view is opened. ( 填写文档类型 : 常问问题 ) P10-13

11 Fig. 05 When composing the SQL filter criterion, the "=" is replaced by the character string "like". This changes the behavior as follows: if the property "MULTI_INSTANCE = no" (default) and if the faceplate is of the type "MOTOR", then there is display of all the messages whose "origin" begins with the same character string as the messages of the "MOT" block. For this reason the additional blocks for displaying the current and current monitoring is called "MOT_IMEAS". Warning! Note that this change is undone by default when the OS project editor is run. To prevent this, you can make the change in the script in the template picture of the OS project editor. Changes in the template pictures or standard functions might be lost when the OS project editor is run or the software updated (installation of a new version of WinCC, a service pack or a hotfix). Additional configuration steps for the group display The same applies here for configuration of the group display as described in Point 2. 5 Create new AS block that internally contains the "MOTOR" and "MEAS_MON" blocks With this method you create a new block that contains the "MOTOR" and "MEAS_MON" blocks. In this way the messages of the "MEAS_MON" block receive the same origin text at Runtime as the messages of the "MOTOR" block. The current monitoring messages are therefore displayed by default together with the messages of the "MOTOR" block in the faceplate. You can create this block in the "SCL", "STL" or CFC editor. The following figure shows the overview of a CFC chart that was used to create the new block. All the block connections of the "MOTOR" and "MEAS_MON" blocks have been created as new block connections and interconnected with the original block connections. ( 填写文档类型 : 常问问题 ) P11-13

12 Fig. 06 The CFC chart was compiled via "Chart > Compile > As block...". The following figure shows how the newly created block is implemented. The "MEAS_MON" block for displaying the motor current has been added to the "MOTOR" block. Note: The block connections that begin with the character string "MEAS_" or interconnected internally with the "MEAS_MON" block, the others with the "MOTOR" block. Fig. 07 Entry describes the settings of this block in detail. Additional configuration steps for the group display When compiling the OS, precisely one tag is created for the new block in the Tag Management of the OS, which contains the group value of both "ALARM_8P" message blocks ("MOTOR" and "MEAS_MON").
