Amit Posted May 23, 2023 Report Share Posted May 23, 2023 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...
AlexUT Posted May 23, 2023 Report Share Posted May 23, 2023 @Amit Are you sure you selected right PLC? Jazz has only 1 communication channel and in your case this make not possible online view and debug. Quote Link to comment Share on other sites More sharing options...
Amit Posted May 23, 2023 Author Report Share Posted May 23, 2023 Hi @AlexUT I had no choice, all others Unitronics PLC had 6-month backorder. this Festo controller connects to an electric actuator that needs to move X distance and go back to zero, so I don't need any feedback from the Festo controller.
