Table 6.16 MEMOBUS/Modbus Communications Error Codes
Error Code
(Hex.)
Name Cause
01 Function Code Error The PLC set a function code that was not 03, 08, or 10 (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.
• The data to be written to non-consecutive holding registers contained more than 60 bytes.
• In the write mode, the number of bytes in the message is not the number of data × 2.
21 Data Setting Error
