We have a Motorola MOSCAD system that talks to a number of sites and lists of addresses for various inputs at each site. For example...

```python
306146:01
306146:02
306146:03
306146:04
306146:05
306146:06
306146:07
306146:08
306146:09
306146:10
306146:11
306146:12
306146:13
306146:14
306146:15
306146:16
306402:01
306402:02
306402:03
306402:04
306402:05
306402:06
306402:07
306402:08

```

We have an Automation Direct MODBUS gateway that lets us communicate with the MOSCAD unit using Ethernet instead of RS232 so we can keep the existing Wonderware system in place while we convert everything to Ignition and test.

I'm having trouble figuring out how to add the addresses. I have the device configured and it's connected, but I haven't had any luck figuring out the addressing. I understand that 3 is an input register and the other MODBUS conventions. I just can't figure out how to get it in Ignition.

Thank you,  
Chris

`306146` is probably something like `[Device]IR6146` in Ignition.

If that suffix is a unit/slave id, then maybe `[Device]1.IR6146` etc...

See [Modbus Addressing | Ignition User Manual](https://docs.inductiveautomation.com/docs/8.1/ignition-modules/opc-ua/opc-ua-drivers/modbus/modbus-addressing) for the address syntax used by the Modbus driver.

I suspect the suffixes are bits. So, `[Device]1.IR6146.0` through `[Device]1.IR6146.15`

Thank you! I was trying to add the addresses under Device configuration but, after reading your responses, realize I don't need to do that.

Thank you,
