Q:
I bought from another vendor one of your product named N4D8C12. I dont find any Modbus command for read any input up to 8. Can you send me other modbus command to read the other 4 inputs?
I am building some tester with your products and i'm very interested in it.
I already have this manual but it hasn't the command i ask. How can i read the input n 8,9,10,11,12?
A:
Dear friend, MODBUS RTU 03 instruction is a read instruction. It supports reading multiple registers.
1-8 input port: 01 03 00 81 00 0C 15 E7
8-12 input port: 01 03 00 88 00 05 05 E3
