These errors may occur when you use the MEWTOCOL protocol for the selected COM interface (error codes in hex numbers).
Error number: |
Cause: |
Remedy: |
|---|---|---|
16#21 |
Data error caused, for example, by a parity or framing error. |
Both devices (PLC and FP-I4C) must have the same communication settings. |
16#23 |
Station number overlapping with another node. |
Change the station number so that there is no overlapping. |
16#24 |
MEWTOCOL format not correct. |
Check the MEWTOCOL format. |
16#25 |
PLC hardware error. |
Try to power off and power on the PLC. Make sure there is no ambient noise around the PLC. If the problem persists, the hardware is probably damaged. Please contact the technical support. |
16#26 |
MEWTOCOL station number out of range. |
Change the station number to a valid value (1 to 64). |
16#27 |
MEWTOCOL frame overload error (more characters than allowed). |
Check the MEWTOCOL request and make sure it does not contain more than 118 characters. |
16#28 |
No response from device. |
Retry to send the request. |
16#29 |
Buffer of the PLC not available during the request. |
Make sure that the buffer in the PLC is available. |
16#30 |
Timeout of data transfer. |
Retry to send the request. |
16#36 |
Station number does not exist in the network. |
Enter a correct station number. |
16#38 |
Other communication error. |
Retry to send the request. Both devices (PLC and FP-I4C) must have the same communication settings. |
16#40 |
BCC error. |
Make sure there is no ambient noise around the PLC. If the problem persists, please contact the technical support. |
16#41 |
Format error. |
Please contact the technical support. |
16#42 |
The MEWTOCOL command is not supported by the PLC. |
None |
16#43 |
Multiple frames received by PLC. |
Wait until transmission has finished. |
16#60 |
Parameter error. |
Please contact the technical support. |
16#61 |
Data format or data range error. This error occurs, for example, when the memory area specified in the read request does not exist on the PLC (e.g. DT70000 does not exist on an FP0H PLC). |
Correct your settings. |
16#63 |
The current PLC mode (RUN/PROG) does not support the transmitted command. |
Change the operation mode of the PLC. |
16#65 |
Read or write protection error. |
You cannot write data to a PLC that is protected by a password. If the PLC is not password-protected, check the access restrictions on the Port page. |
16#66 |
Address error. |
Please contact the technical support. |
16#67 |
Reading is not possible because there is no data in the specified memory area. |
Change the memory area. |
16#72 |
PLC reception timeout. |
Retry to send the request. |
16#73 |
Receive buffer of the PLC not available during the request. |
Make sure that the buffer in the PLC is available. Do not use it for other purposes. Retry to send the request. |
16#74 |
Response timeout. |
Retry to send the request. |
