Ok answering my own question, maybe someone will find it useful: place python sop in foreach block, and in there:
your_cop_node.parm('execute').pressButton()

Ok looks like I can do this with a python script, using render() method on a rop node. Is there a simplier way?

How do I force the ROP File Output to render a COP image matrix to a file when the network changes instead of manually pressing a button? I run operations in for-each loop and the COP is updated each iteration. Thank you in advance.
