22 “MPXPRO” +030220186 - rel. 1.0 - 22.05.2007
E N G L I S H
MPXPRO can manage a maximum of 11 analogue probes: 7 can be physically connected to the device
and 4 serial probes via the master-slave network. The possible configurations of the parameters and the
corresponding meanings are shown in the following table.
/FA /Fb /Fc Probe associated
0 No probe associated with the function, probe not present
1 S1 (default /FA)
2 S2 (default /Fb)
3 S3 (default /Fc)
4 S4
5 S5
6 S6
7 S7
8 S8 (serial probe)
9 S9 (serial probe)
10 S10 (serial probe)
11 S11 (serial probe)
Tab. 5.c
The default values of parameters /FA, /Fb, /Fc identify a typical application that uses three temperature
probes to control the temperature inside the cabinet. There are cases however in which the features of
the applications require different settings.
Examples:
Control inside a cold room is normally performed using two temperature probes, specifically the intake
temperature is not used. In this case, the possible configuration may be:
/FA=1: Outlet temperature measured by probe S1 (Sm=S1)
/Fb=2: Defrost temperature measured by probe S2 (Sd=S2)
/Fc=0: Intake temperature absent
Alternatively:
/FA=1: Outlet temperature measured by probe S1 (Sm=S1)
/Fb=3: Defrost temperature measured by probe S3 (Sd=S3)
/Fc=0: Intake temperature absent
/t1 Select display on the main terminal
Code UOM Min Max Def.
/t1 - 0 14 12
If the device that is being configured has its own main terminal (user terminal with keypad), parameter
/t1 can be used to select the probe whose value is displayed during normal operation.
Value of /t1 Probe displayed
0 No probe displayed
1...7 S1 to S7
8...11 S8 to S11 (serial probes)
12 Sreg (Control probe) Default
13 Sv (Virtual probe)
14 Set point
Tab. 5.d
To configure the value shown on a second display, see advanced parameter /t2.
5.1.3 Digital inputs
Based on the configuration of the probes, MPXPRO manages up to 5 digital inputs, directly connected to
the board, and 1 virtual digital input shared by the master with the slaves across the local network.
The function of each individual input depends on the setting of a specific parameter. The following are
used parameters to set the functions of the digital inputs:
Parameter DI
A4 DI1
A5 DI2
A10 DI3
A11 DI4
A12 DI5
Tab. 5.e
For the configuration of the virtual digital input, refer to parameters A8 and A9.
The possible functions are identical for each digital input.
A4 - A5 - A10 - A11 - A12 Digital input configuration
Code Name UOM Min Max Def.
A4 Configure function of digital input DI1 on S4 - 0 7 0
A5 Configure function of digital input DI2 on S5 - 0 7 0
A10 Configure function of digital input DI3 on S6 - 0 7 0
A11 Configure function of digital input DI4 on S7 - 0 7 0
A12 Configure function of digital input DI5 - 0 7 0
