PM5x1 Ethernet 'No Socket Available
Im trying to access data from nine PM556-ETH PLC's to my main PLC PM573-ETH using ETH_MOD_MAST, but iam unable get data, I have assigned %MW0.101 series of memory address to thoes tags whose data i need at my main plc.
At ETH_MOD_MAST block iam getting error no "12325".
sometimes data comes for few seconds but after that it freezes. error saying "#51654404 - PM5x1 Ethernet 'No Socket Available"
i have even configured ethernet extension CM597 and assigned IP Address too.
I am not getting what am i doing wrong.
Please Help, Thank You
- EN input should be pulsed (help:If a FALSE -> TRUE edge is applied to input EN, all further inputs are read in). Try using ICR.EN:=NOT(ICR.DONE);
- IP_ADR should be the IP addrress of the slave you are reading from
- Error code says:
ETH_MOD_MAST: Cannot connect to server (IP address) OR response telegram contains wrong UNIT_ID (must be the same as in request).
- UNIT_ID - help says:
At input UNIT_ID, the address of the MODBUS slave must be specified which is connected serially to the MODBUS server defined by IP_ADR. If no further slaves are connected, this input is not used
Try with set 0 to this
- ADDR - why you set 100 when you are looking for %MW0.101 ?
