The software protocol used for supervisor/CONTECA
®
environment
interfacing utilises the M-Bus standard (complies with EN 1434 part 3).
N.B.:
The transmission bus, code 755855 LSC, is two-way (cross-section 2
x 1 mm
2
). The controller allows max. 250 users.
The maximum length of each individual section is 1200 m.
It is possible to lay up to 4 separate sections using the MULTIPLEXER,
code 755005.
