DIRIS Digiware M-50 & M-70 - 548751B - SOCOMEC
9. AUTOMATIC DETECTION OF DEVICES
Once the system is fully wired and powered, you must launch the auto-discovery process by pressing the “ADDR.”
button under the M-50/M-70 for 3 seconds.
The auto-discovery process will discover devices connected to the Digiware bus and RS485 bus and assign them with
a unique Modbus address.
2 auto-discovery modes can be used:
- FAST (default mode): this mode will only detect DIRIS Digiware modules on the Digiware bus and RS485 bus,
DIRIS B and DIRIS A-40 on the RS485 bus.
- FULL: this mode will also detect other Socomec PMDs (DIRIS A) and meters (COUNTIS E) connected on the
RS485 bus.
The EasyConfig System software must be used if you wish to change the auto-discovery process mode to FULL.
If multiple devices have the same Modbus address (which is common as multiple modules and devices may come out
with the same factory default settings), there will be an address conflict during the auto-discovery process which is
perfectly normal. All devices with an addressing conflict will have a fixed COM LED.
To resolve address conflicts, press the front button of each module that has a fixed COM LED for at least 2 seconds.
Notes:
• The order you will use to press the push buttons on the modules will also determine the order for the
Modbus addressing of those modules.
• The auto-discovery process can also be launched from the EasyConfig 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 adresses to the devices connected to the M-50/M-70
gateway, their Modbus address must be manually changed using the EasyConfig System software, before
launching the auto-discovery process.
