Name
The PLC set a function code that was not 03, 08, 10, 5A, or 67 (Hex.).
• 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.
• 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.
• Writing control data or parameters made the settings go out of the permitted setting range.
• A parameter setting error occurred when writing a parameter.
