RCL
The Modbus interface, used to communicate with a GTC, is available as an option, factory
assembled or with a kit.
Caution
The use of the µBMS recall command is not compatible with the modbus communication. The
same terminals and addressing DIPs are used in both connection cases.
Caution
Shielded twisted pair wire must be used for interconnecting wiring. Wire impedance must be
between 100 and 130 Ohms and the wire surface section must be between 0.12 and 0.5 mm² (26
to 20 AWG). Larger wire may be used, but in this case connection to the terminal blocks can cause
problems.
Caution
28 SYSHRW
The MODBUS supervision can be connected to a maximum of 123 appliances.
²
The maximum distance between the RCL and the first unit is 30 metres.
²
The maximum distance between the RCL and the furthest unit is 100 metres.
Note
: When MODBUS supervision is used, all the units must have a unique address (see "Addressing
procedure").
