Connecting two IOMod 16DI
Description
This article describes how to connect and configure two IOMods 16DI to the WCC Lite using IEC103, and Modbus RTU.
Typical connection schematic for two IOMod 16DI
WCC Lite can be connected to two IOMod 16DI via PORT1 or PORT2.
Preparing the configuration
At first you need to make a configuration for the WCC Lite. This can be done using any spreadsheet editing program. Templates for configuration can be found on the WCC Lite web. Protocol Hub --> Configuration. On the bottom of the page there will be a Download button for template configurations.
You need to configure Devices and Signals sheets before continuing. These template configurations can also be used to configure protocols like Modbus-master and DNP3. Configuration can be modified according to functionality needed. In this case, Device sheet will only have three devices, WCC Lite and two IOMod 16DI. It is important to use only one protocol for each port, otherwise configuration will not work.
You can download the example configuration for each firmware versions at the bottom of the article or create your own using these links:
You need to configure Devices and Signals sheets before continuing. After downloading template configurations, open phub templates folder. You will see that there's different template folders for each IOMod:
To select correct configuration, check the sticker on the back of IOMod. There you will find which protocol to use according to Factory FW type. For example, if you have IOMod 16DI with IEC103 FW, select configuration iomod_16DI_IEC103_to_IEC104_DNP3_Modbus_SCADA.
Before connecting IOMods to WCC Lite you need to configure it via mini USB. This can be done following IOMod 16DI user manual.
You need to configure it, like it is done in the excel configuration. To do that, fist you need to open IOMod utility app and change these parameters: baudrate, parity, link address. It is important, that link addresses for both IOMods are different and parity and baudrate should be even. Other parameters such as databits and stopbits should be set to default. Signals sheet should be mapped according to functionality needed.
Uploading configuration
After configuration is ready, upload it to WCC Lite (Configuration --> Choose file --> Import configuration):
After upload is done and no errors were detected, you should see all imported signals (Protocol Hub --> Imported signals):
Before doing anything further you should also check for protocol connections if both IOMod 16DI are connected to WCC Lite via PORT1. Go to Protocol connections where you can see all the connected slave and master protocol devices:
Connecting IEC104-slave via Vinci
After Excel and USB configurations, you can connect to device using Vinci software. In order to simulate IEC104 slave you need to choose IEC 60870-5-104 protocol and Master(Client) mode and press start. In Settings tab, check Structure, Timeouts and Windows values to match Excel configuration.
Then set correct IP address and Port at the top of the program page. Port for IEC104 should be 2404 and IP address should match your WCC Lite IP address.
After clicking start, you should check protocol connections tab again to see if IEC104 slave is connected.
Once IEC104 slave is connected, console tab in Vinci software should look something like this:
If you want to configure IOMod 16DI, you should refer to -> IOMod 16DI User Manual.
