It's very simple, two ways:
1. you can use a CIM 620-0043 Module from Honeywell. This module supports Modbus-RTU (seriell), then you can use a Modbus/ModbusTCP "converter" (Digiport, Lantronix,...) if you want use the ethernet.
I've never used a Data Station Plus, but from the manual off Red Lions' web site it looks like the Data Station Plus can act as a DIN rail mount comm master to act as a go-between the Honeywell 620 and an HMI.
Apparently the Data Station Plus is a model G3 HMI, minus the screen, with all the master comm capabilities inherent to an HMI. If you are looking for an HMI, I suspect that the G3 series could handle the HMI tasks, standalone.
John,
It depends on the specific model of 620 system you have. The newer ones
(-11, -12, -14, -16, -36) have built in ports that talk Modbus RTU, enabling
you to use either a built in driver for Modbus RTU or an OPC client in
WinCC.
For the older systems (-06, -10, -15, -20, -25, -30, -35) you need to buy
and install a 620-0043C in each system. This module also speaks Modbus RTU.

If you are interfacing to the IPC620-12, 620-16 or 620-36 processor, there is a port on the processor which will run Modbus RTU with either RS-232 or RS-422/485. I have sucessfully interfaced to Honeywell DCS through their serial input ports.
If you are using the other processors (620-06, 10, 15, 25 or 35), there is a modbus module which can be added to the I/O rack. I believe that this will require the addition of coding to place the desired information in the module.
Although I haven't worked with them, I believe that the 9000 series processors have a 10Base-2 port on them.
The older 620s (620-15/20/25/30/35) had no integrated comms - they require an additional card to be placed in any avaiable option slot in the processor chassis. A 621-0042 or 0048 give a single serial port with Honeywell ABC protocol whist a 620-0052 gives dual ports. Both can be either RS232 or 422 and require no programming what so ever in the PLC. There are many MMIs and SCADA that support ABC (For example Moeller XVs, Red Lion/Pardigm text displays, Intelution Fix SCADA etc).
Newer processors (620-12/13/14/16/26/36) have an RS422 port on board which supports ABC or Modbus RTU. Modbus is also available in the form of an option card (620-0043) but is hard to find.
