The controllers are programmed by dipswitches and trimmers in the MAN
mode, or by setting the internal parameters - in MEM mode, accessible
via programming key or via serial line.
4.1 Manual and standard internal
parameter programming
The functions that can be set manually using the dipswitches and
trimmers (Fig. 4.aa) are shown in the tables below, complete with the
Modbus variables used to read the manual settings.
ADDRESS
Mode dipswitches (S2)
Function
Dip S2.1
Select type of controller setting
Dip S2.2
Select type of analogue inputs
Dip S2.3
Select voltage/current input
If dipswitch S2.1 is ON, the standard internal parameters are used,
equivalent to those that can be set on the panel. These have the same
name, however with the suffi x MEM rather than FCR.
Function
Select operating frequency
Select operating curve
Select null input mode
Select baud rate for serial operation
MINIMUM setting (MIN)
MAXIMUM setting (MAX)
DELAY setting (DELAY)
Input control (IN)
The address parameter can be automatically selected, based on the
dipswitch settings. For details, see Table 4.a.d
Function
Select FCR address (ADDRESS)
DI = Discrete inputs
R digital variables
CO= Coils
R/W digital variables
IR = Input Register
R integer variables
HO= Holding Register
R/W integer variables
The digital variables are interpreted as 0=OFF , 1 = ON
