4. . Operation via Modbus
The unit can be operated via the b-touch control panel and via
Modbus. This chapter describes the operation via Modbus.
n Some settings and functions can only be used via the
b-touch control panel or, conversely, only via Modbus.
4.1 Frequently used register addresses
This paragraph describes frequently-used functions and their
corresponding register addresses.
c Do not adjust other register addresses without
consulting Biddle.
n It may occur that the system applied uses a value of
1 higher than the register addresses given here. In
that case, use 101 for register address 100, for
example.
n For functions that are also in the b-touch panel, the
corresponding menu parameter is shown between
brackets after the register address.
Menu parameters 0 - 1 are functions in the home
screen.
n Settings in the b-touch control panel can cause
Modbus settings to be ignored. In register addresses
410 to 419 inclusive, it can be specified whether
settings may be altered via the b-touch.
Register addresses 410 - 419 are related to 400 -
409 and 420 - 429 respectively.
