(Hex.)
Name
Cause
01
Function Code Error
The PLC set a function code that was not 03, 08, 10, 5A, or 67 (Hex.).
02
Register Number
Error
•
The register number that is trying to access is not registered.
•
A starting number that was not 0001 or 0002 (Hex.) was set when broadcasting.
03
Bit Count Error
•
Read and write data quantities are more than the 1 to 16 range. (Command message data
quantity is disabled.)
•
The data that was read from non-consecutive holding registers contained more than 120 bytes.
•
