Amit Posted May 23 Report Share Posted May 23 Hi, I'm a newbie with plc ModBus protocol (as well as with the Jazz ) and trying to connect the jazz to control Festo electric actuator with CMMO-ST controller. i have JAZZ JZ20 J R16 with MJ20-ET1 module and FESTO CMMO-ST i read all the info that i can get from Unitronics U90 help and Festo CMMO-ST but still, i don't understand how i actually code the U90 ladder to control the Festo controller. i searched in the net and didn't find any example for that. I'm using FESTO TCP client app. and as far as i understand the FHPP out is what i need to output from the jazz and FHPP in is what i need to read back. but how do I Actually send the THPP out with the U90? Best regards, Amit. 🍻 Quote Link to comment Share on other sites More sharing options...
