wjm Posted September 1, 2022 Author Report Share Posted September 1, 2022 Hello, how can I see the modbus addresses are assigned during programming? I am an end user of the device and I received this as an address table: MB3150 alarm synthesis Threshold 1 Bool 0 1 MB3151 alarm synthesis Threshold 2 Bool 0 1 MB3152 Synthesis of sensor fault Bool 0 1 I don't know how to translate this for a com with my Flexy 205 and I didn't have the com parameters either; address, port, speed... how can i get rid of it? thank you jm Quote Link to comment Share on other sites More sharing options...
DanT Posted September 2, 2022 Report Share Posted September 2, 2022 Hi; In the Unitroncis Vision PLC, all the MB's (Memory Bits) and MI's ( Memory integers ) used are accessable by Modbus Reads and Writes. MB's are Modbus Coils MB3150 is Modbus Coil 3160 MI's are Modbus Registers MI 100 is Modbus Register 100 For efficiency of Modbus Reads and Writes, the programmer will probably lump MB's and MI's in groups that they know will be Sent or Read by Modbus commands. Getting the Com Parameters Ask the supplier of the PLC. OR The way of checking for the Com Parameters is via the Info Mode. On a touch screen PLC, press an area of the screen not activly used for touch for about 6-9 seconds. Enter Info Mode -- Password 1111 Choose Serial or Ethernet and explore.
