Summary
Communication Driver Information | |
|---|---|
Driver name | OmronCIP |
Implementation DLL | T.ProtocolDriver.OmronCIP.dll |
PLC types supported | NX-Series (tested with NX102-9020) |
Manufacturer | OMRON |
Protocol | OmronCIP (CIP over TCP/IP) |
Interface | TCP/IP |
PC Requirements | Ethernet board |
Channels Configuration
Protocol Options
Model: Set the PLC model.
It can be:
NX-Series: For all models in the NX-Series and compatible.
Nodes Configuration
Station Configuration
Stations syntax: <IP>; <Port>; <Slot>
Where:
<IP> = IP address of the slave device in the network
<Port> = TCP port where the slave device is listening (default is 44818)
<Slot> = Slot is the Slot number where the CPU is connected.
Nodes Configuration Example
Name | Channel | PrimaryStation | BackupStation | Description |
|---|---|---|---|---|
Node1 | OmronCIP | 192.168.1.101;44818;0 | OmronCIP [OmronCIP Communication Driver] |
Points Configuration
Address Column Configuration
The syntax for ControlLogix communication points is:
<Type> : <DeviceTagName>
<Type>: Data type of the Tag in PLC.
The valid type values are:
Type | Read | Write | Size |
|---|---|---|---|
BOOL | Yes | Yes | 1 bit |
SINT | Yes | Yes | 1 byte or 8 bits |
INT | Yes | Yes | 2 bytes or 16 bits |
DINT | Yes | Yes | 4 bytes or 32 bits |
REAL | Yes | Yes | 4 bytes or 32 bits IEEE Floating point |
LREAL | Yes | Yes | 8 bytes or 64 bits IEEE Floating point |
STRING | Yes | Yes | n bytes |
DeviceTagName: Tag Name in PLC.
Troubleshoot
The status of the driver execution can be observed through the diagnostic tools, which are:
- TraceWindow (with Settings / Device enabled)
- PropertyWatch
- ModuleInformation
The status value of 0 (zero) means communication success. Negative values indicate internal driver errors and positive values indicate protocol errors.

31 | Failure during connection. |
34 | Invalid reply received. |
37 | Key segment error. |
38 | Number of IOI words specified does not match IOI word count. |
39 | Unexpected attribute in list. |
For this driver, it is very important to enable the TraceWindow messages, as invalid addresses can cause all the communication block with the PLC to fail. The TraceWindow tool will display the first invalid address found on the block. To enable Device error messages, open the TraceWindow and click on the Settings button. Enable the Devices option in Modules.
In order to have a quick view on the many communication blocks, open the ModuleInformation, navigate on the tree to find OmronCIP and them select the Read Groups. Looking at the success and fail communication counters, you can easily identify if there is a block with errors and then use TraceWindow to locate the wrong address.
Solution OmronCIP Driver -200 Fault
Using the OmronCIP driver to communicate with an Omron NX-102 PLC.
Decrease the value of your MaxSimultaneousConnections property. If it is set to 5, you can try to decrease it to 4 or 3. Besides that, you can try to decrease the value of NodeConnections too. These properties can be found in Edit > Devices > Channels > Settings, like the image below:
Add value 3 to retry property, in Edit > Devices > Channels > Timeout, like the image bellow:
