How do I connect an HMIGTO with a Zelio SR3 Smart Relay?

Published date: 13 April 2020

Issue
The HMISTO501 along with the VJDSTKSTOSR2 (HMISTO and Zelio Starter Kit) is now obsolete. What is an alternative HMI that I can use to connect to Zelio SR3 Smart Relay?

Product Line
Zelio ZR3 Smart Relays, HMISTO501, HMIGTO

Environment
Physical HMIs and Smart Relay connectivity

Resolution
The HMIs that currently support connection with Zelio SR3 smart relays are the HMIGTO series starting with the HMIGTO2310 and larger (only COM1 RS-232 Dsub9 connectors can be used on the HMIGTO).
To program, use Vijeo Designer v6.2 and ZelioSoft 2.

You will also need the SR2CBL09 cable to directly connect to the Zelio from the HMI's COM port.

The HMI to Zelio cable SR2CBL09 has the following pinout:
Green wire - goes to HMI's SD(TxD) - Send Data - pin 3
Black wire - goes to HMI's RD(RxD) - Receive Data - pin 2
Red wire - goes to HMI's ER(DTR) - Data terminal Ready - pin 4
White wire - goes to HMI's SG - Signal Ground pin 5

Pinout diagrams for the HMIGTO can be found in the Harmony HMIGTO for Vijeo Designer, User Manual:
https://www.se.com/ww/en/download/document/EIO0000001133/

In Vijeo Designer, you will need to add the Driver from the IO Manager with:
Manufacturer = Schneider Electric Industries
Driver = Zelio Logic Smart Relays
Equipment = Zelio Logic Smart relays


In ZelioSoft 2, use the "SL In" and "SL Out" Blocks from the FBD menu:

The values in "SL In" pins 1 through 8 will be read from the HMI's registers of the same name.
The values in "SL Out" pins 1 through 8 will be written to the HMI registers of the same name.
