In step 7 i know how to monitor individual block calls. but in TIA how to monitor the individual driver calls. Ex: motor driver fb1 motor calls fb2. here i called the FB1 5 times i called the FB2 in OB 1. how to monitor the 4th motor?

Hi

This is how you can set the Call environment in TIA :

Setting the call environment of the block

By setting the call environment, you can specify when the program status of a block is recorded.

The section " Setting the call environment for breakpoints" describes how to set the call environment for breakpoints.

Requirement

The block is open.
The CPU is in test mode.
See also: Specifying the mode

Procedure

To set the call environment, follow these steps:

Open the "Testing" task card.
Click the "Change" button in the "Call environment" pane.
The "Call environment of a block" dialog opens.
Select the condition you want to apply.
See also: Basics of the call environment
Confirm your selection with "OK".

Hope this helps

Cheers

Navnag

There is no such thing as the last bug in a program

I have the following: Function Block AC Instance Data Blocks AC1_DB, AC2_DB From OB1, AC is called first with AC1_DB then with AC2_DB. How can I monitor function block AC with a particular instance data block? I could not find any CPU test mode or any way to edit the call environment. The logic appears to be working correctly but it would be reassuring to be able monitor each instance.

In this case, the alternative is change (if possible) the blocks call order, once to monitore the first call of it.

We have been waiting on this but it is not there. If you are using the TIA Portal with a 300 you can do that, but not with the 1200."

We have been waiting on this but it is not there. If you are using the TIA Portal with a 300 you can do that, but not with the 1200." You can now change the call environment when using an S7-1200 having firmware 4.0 under TIA V13. Go into the (multi-instance) FB you wish to monitor. Then from the drawer on the right, select "Testing" and then under "Call environment" push the "Change" button. From there you select which DB will be monitored with the FB you have open. -- When using TIA V13 Professional with PLC Simulator, you can test S7-1200 coding. You have to create the coding inside an S7-1500 PLC to simulate it. When you simulate the code, you can click on the block call of the FB you wish to simulate and ask "open and monitor". The correct instance (call environment) will open. You will see the FB with the right DB opening for monitoring. -- If you wish to monitor a multi-instance FB and your S7-1200 is not of firmware 4.0 - make sure the block calls are arranged so that you call first the FB you wish to monitor. If you have firmware 2.2 or 3.0 you should be able to change the order of the calls wihtout needing to place the PLC in STOP mode. Helpful? w
