How to set an end node for Omron E5CC Temperature Controller communication line?
If an end node has not been set at each end of the communications line on your Omron Temperature Controller, set or connect terminating resistance at each end of the line.
How long to wait before sending the next command to Omron Temperature Controller?
If the host device sent the next command too soon after receiving a response from the Controller, wait for at least 2 ms after receiving a response before sending the next command.
What is the maximum number of devices for Omron Temperature Controller communication path?
If too many communications devices are connected to the communications path on your Omron Temperature Controller, when 1:N, RS-485 communications are used, a maximum of 32 nodes may be connected, including the host node.
What type of communication cable should I use for Omron E5CC Temperature Controller?
If the wrong communications cable has been used for your Omron Temperature Controller, use shielded twisted-pair cable for the communications cable.
What to do if temperature error is large on Omron Controller (S.Err display)?
If you are seeing a large temperature error or an S.Err display on your Omron Controller, it may indicate an input type mismatch. Check the sensor type and reset the input type correctly.
How to synchronize baud rate and communication method on Omron Temperature Controller?
If the same baud rate and communications method are not being used by all of the Controllers, host devices, and other nodes on the same communications line, set the same values for the following on all nodes: baud rate, protocol, data length, stop bits, and parity.
What to do if the Omron E5CC Temperature Controller communication cable is broken?
If the communications cable is broken on your Omron Temperature Controller, replace the cable.
Why is the communication indicator on my Omron E5CC Temperature Controller PLC not lit?
If the communications indicator on the PLC is not lit, it could be due to several reasons: * The power supply is not turned ON to the E5@C Controller with communications unit number 0. * The wiring is not correct. * The communications settings are not the same between the PLC and the E5@C. * The E5@C was moved to the initial setting level (setting area 1). * Check the cycle time of the PLC. If it is longer than the value set for the Receive Data Wait Time parameter, change the set value of this parameter so that it is longer than the cycle time.
What to do if the Omron Temperature Controller communication line is disconnected?
If the communications line has become disconnected on your Omron Temperature Controller, connect the communications line securely and tighten the screws.
How to fix incorrect communications wiring on Omron Temperature Controller?
If the communications wiring is not correct on your Omron Temperature Controller, correct the wiring.
