1. Start the auto-discovery of all devices connected to the Digiware or RS485 buses, by pressing the “ADDR.” button
under the M-50/M-70 for 2 seconds.
2. “COM” LEDs of all devices will start blinking synchronously during the process. If com LEDs are not blinking, there
could be a configuration issue (inconsistent baud rate between the M-xx gateway and slave devices).
3. After approximately 1 minute, the COM LED of the M-xx gateway as well as I-xx/S-xx/IO-xx modules are lit and stable.
This is perfectly normal; it simply indicates that address conflicts have been detected since multiple devices have the
same Modbus address (same factory default settings).
4a/5a. Press the front button on each slave device that has a fixed COM LED, for 2 seconds to resolve address conflicts.
4b/5b. COM LEDs of the modules start blinking again.
6. COM LED of the M-xx gateway starts blinking again, and slave devices can now communicate with the M-xx gateway.
7. The auto-discovery process is finished, the COM LEDs blink when communication is on-going between the M-xx
gateway and downstream modules.
Notes:
•
The Easy Config System software must be used if you wish to change the auto-discovery process mode to FULL.
• The order used when pressing the push buttons on the modules also determines the order for the Modbus addressing
of those modules.
•
The auto-discovery process can also be launched from the Easy Config System software where you can choose an
automatic resolution of conflicts, instead of having to press the front button on the modules.
If you would like to assign specific Modbus addresses to the devices connected to the M-50/M-70 gateway,
launch the auto-discovery from the Easy Config System software, and change the Modbus addresses of slave
devices directly from the dashboard of the M-50/M-70 gateway (see 13.2).
