BarP Posts: 10 Rating: (0)	hi,I have a problem with module Modbus 6ES7 138-4DF11-0AB0 and module Counter 6ES7 138-4 DA03-0AB0 C. May i use these module together with one IM151 6ES7 151-1AA04-0AB0? In standart case my communication run OK, but whenI receive input signal to thecounter module communication froze. WhenI see to the led on the modules I see, that led on the Modbus module quicken blinking whenI recieve input signal to the counter module.Diagnostic SFCERR in this time indicate none err. Sorry my english is limited. BarP

For the Modbus communication you need the newest communication blocks, did you check that? This link doesn't seems to work... Is the 1SI Module up-to-date, see Operating system updates for ET200S 1SI (ASCII, Modbus)? See also the restrictions in the FAQ Which hardware components / interfaces can you use to connect the PtP CPs CP 340, CP 341 and the ET 200S 1SI module in a PROFIBUS DP, PROFINET IO network or to an IE/PB link?
	I hope that the answer will help, if you have still questions, don't hesitate to ask me. All the best, Late Never say never, think in solutions, not in trouble......
