AjaS Posted July 4, 2019 Report Share Posted July 4, 2019 Hi all, I use USC-P-B10 with USP-070-B08 (modular HMI/PLC) as a master via Modbus Ethernet. Could anyone recommend me how to catch an exception in UniLogic 1.26.90 if slave is not responsive (powered down, loose cable...). Thanks Link to comment Share on other sites More sharing options...
