7.1.3.I/O modules readings
• I/O modules readings
Insite pro M allows to connect up to 8 I/O modules (in the case no other device is connected – maximum
device count is 32 and one I/O module counts as 8 devices). I/O modules can be assigned to Modbus ID
from 1 to 32 and can be read/control using web UI and Modbus TCP/RTU protocols.
For direct reading using Modbus protocol, IO module registers map is provided below.
Please note that addresses 0-3 (status contacts) could be read using Modbus function 01 (read coils) as
well as function 03 (read holding registers). All other registers are being read with function 03.

7.1.4.ABB meters readings
SCU200 allows connecting up to 16 RTU devices including meters with RS-485 interface. Supported meter
types are ABB M4M/M1M, M2M, DMTME, IM300, EV meters and EQ meters. Each meter can be assigned to
Modbus ID from 33 to 48 and is available under My plant->Devices->Modbus RTU devices.
After adding RTU device with specific type, the device is scanned for responding registers. In case if 3rd
party RTU device is added outside of known device models, user should upload own device descriptor
which will be used by SCU200 for creating device registers map.
RTU devices don’t have to have uniform Modbus configuration. SCU200 will adapt readout coniguration in
case if different devices have different baudrates, parities etc. If a device stops responding (disconnects,
encounters fault or because of any other reason), it will be excluded from readout queue for an hour. After
an hour another readout attempt will be made and once responds correctly, it will be read as usual.
