Regarding the errors in the PM573 PLC
We are using 7 PM573 plc's in a network. in those 7 plc's two plc's are getting errors. The error type is E4. The E4 error are warnings. the error are
online no is : 153286827 and 151654404.
i have gone through the error list i found the discription as
153286827 : SRAM disk has been formated.
151654404 : No socket available.
these two errors are displaying in the plc lcd dispaly and also i am checked in the automation builder in the CPU diagnostics.
Please explain the errors are related to and what is the cause of the errors...
E4 error could means problems at pheripheral device in the I/O bus.
Have you tested the connection or change one cpu in E4 state with one other with the same program inside?
If the error is coming at the new cpu, you have one indication about the possible cause of it: the I/O bus and/or the pheripheral connections.
Hope this help you
