Thank you i have succeed with the READ_VAR instruction, but i cannot read more than 125 Words. And another problem is that: after a power failure the communication won't start again until i stop and then rerun the PLC

Hello! I want to realize a communication between a TSX ETY port of Modicon and a Prosoft convertor, via Modbus TCP/IP protocol. I try with IO Scanning but i cannot succed. Can somebody help me to setup ETY Port? Thank You, in advance.

I'm trying to establish communication between a Twido working as a master and two generic Modbus devices (PM710) working as slaves, but I have problems using the EXCHx and MSGx functions. I can only send the first message to the first Modbus device using the EXCHx function. After this, the value of MSGx.D never goes back to one and so the next message using another EXCHx function can't be sent. It keeps sending the first message and receiving an answer from the same slave over and over again. I configured it in the same way it's described in the TwidoSuite V2.0 Programming Software Online Help in the in the description of the Exchange Control Function Block (%MSGx) Transmission of Several Successive Messages. Can anyone please explain me how to Twido acts as a master and sends multiple messages to slaves? Thanks in advance.

I try with the Modbus RTU protocol macro, but still i cannot connect I use the same protocol with a PM500 from Schneider also and communication works fine

Hello As you see in the title i want to make a communication between a Vigilohm XLI300 (by Merlin Gerin) and a omron PLC using SCU41. XLI300 use a modbus protocol named JBUS. Is this communication possible? How to make wiring between SCU and XLI300 Thank You

do you succed? i have 4 slaves and i also cannot read error bit on PMCR

for C1 i use #0000 (Standard calculation method), and for C2 #0006 but still oscillating

i use PRV2 function but the speed rotation don't display a constant (sped rotation oscillating)

hello i have a CP1L plc, and i want to count number of pulses/ time what instruction is for this thank you sorry for my bad english

PRV2 function work for proximity sensors?

I have one proximity sensor which can generate 6 pulse per revision. How can I calculate the RPM? Is PRV2 function available for sensors or only for encoders use? Can me help someone? My PLC is OMRON CP1L-M30DR Thank You in advance Mario
