-1 TimeOut – no response received
Remedy: Increase the set timeout time at the tRxTimeout input.
-2 Response of station does not correspond to read request
-4 Number of the received data bytes does not correspond to the
number of the expected data bytes.
-5 Number of the expected data bytes is higher than the value given at
the nBufferSize input.
Remedy:
• Increase the value at the nBufferSize input.
• Make sure that the variable at the pData input has at least the
same value as the value at the nBufferSize input.
-6 Toggle bit in the SDO response has not changed its value.
-1011 Internal data pointer does not stand on the PLC RAM
-1012 The set CAN identifier (COB-ID) is outside the permissible range
(0…2047)
Remedy: Assign a CAN node address between 1 and 127 to the
nAddress input.
-1118 No free CAN channel is available.
Remedy:
• Do not use one of the CAN objects CAN1_IN … CAN3_IN or
CAN1_OUT … CAN3_OUT.
• Set C2118 to "1" (write parameter via SDO2).
Note: If C2118 = "1", the SDO2 channel is not available anymore!
• Switch off the generation of the sync object (C0369=0).
-1119 The transmit request memory is full. The transmit request could not
be entered anymore.
Remedy:
• Reduce the number of transmit objects.
• Increase the cycle time of the transmission objects.
• Increase baud rate.
Generally, an object is sent every 250 μs.
-1120 CAN driver is not initialised
Remedy: Initialise the CAN driver with the L_CanInit function from
the »LenzeCanDrv.lib« library.
-1121 Wrong driver number
-1150 CAN bus is not in the "Operational" status
Remedy: Configure the system bus interface "CAN on board" of the
PLC target system as master (C0352=1).
-2011 Internal data pointer does not stand on the PLC RAM
-2012 The set CAN identifier (COB-ID) is outside the permissible range
(0…2047)
Remedy: Assign a CAN node address between 1 and 127 to the
nAddress input.
-2120 CAN driver is not initialised
Remedy: Initialise the CAN driver with the L_CanInit function from
the »LenzeCanDrv.lib« library.
-2121 Wrong driver number
-2150 CAN bus is not in the "Operational" status
Remedy: Configure the system bus interface "CAN on board" of the
