Table 5: digital output
Digital outputs are used to switch any kind of ON/OFF devices as well as motorized valves (using 2 digital
outputs in sequence). Depending on controller hardware the output is either a switching relay output (8A /
250V) or a logic output (OFF=0V / ON=12V). The following parameters select the kind of operation (control
outputs, alarms, events etc.). Digital outputs used by the PLC must not be assigned in this section
.
00: output mode
(options END, PRZ, MOT, LIM, PRC, EVE, TAB, CMB, ---)
Selects an operation mode of the digital outputs:
PRZ: Used to provide the output value of a control channel (loop) to an ON/OFF device. The most common
application is to control a contactor used for heating
MOT: Used to provide the output value of a control channel (loop) to a servomotor device. A typical application
when controlling a motorized butterfly valve on a gas kiln. A servomotor is controlled by 2 digital outputs
(OPEN and CLOSE). The physical output CLOSE is automatically assigned to the output following OPEN
LIM: Output works as limit switch (commonly called ALARMs). Any kind of comparison of process of constant
values can be done
PRC: Indication of selectable process conditions. Can be used to activate an output on programme end, process
errors, process holds etc.
EVE: Used to configure the output as programme event. Can be programmed to ON or OFF for each segment.
During programme run the output is set accordingly
TAB: Used to control a group of outputs according to the bit pattern provided in the corresponding column of
the programme table. Typically used in combination with a PLC
CMB: Output is driven according to the result of the network defined by the following parameters. Used to
create simple logic networks, ie. output do0.2 is only if do1.0 and do1.1 is active. For more complex networks
ask for the optional, integrated PLC
01: destination
(value range OFF, DO0.0 to DO0.4)
Selects the physical output of the signal
following parameters apply on selection PRZ only:
02: channel source
(value range CH00 to CH02)
Selects the control channel (loop) used to drive the output
03: output charact
(value range 0 to 5)
Specifies the operation range of the output. Used to limit an output assigned to a heating / cooling loop (range
+100% to -100%) to the physical range of operation. In an typical application one output (eg. controlling the
heating elements) is set to "0 to +100%" and a 2nd output (eg. controlling a fan) is set to "0 to -100%" (both
outputs assigned to the same control channel). The available settings are 0=0% to +100% / 1=+100% to 0% /
2=0% to -100% / 3=-100% to 0% / 4=-100% to +100% / 5=+100% to -100%
04: outp.% on IDLE
(value range 0 to 100)
Whenever the controller is IDLE the output is fixed to this value
05: outp. % on ERR
(value range 0 to 100)
Whenever the entire controller is in ERROR status the output is fixed to this value. Note that this only applies
on system errors and not an operation error on a single channel
06: min. output %
(value range 0 to 100)
Lower output signal limit. The output will never drop below this limit. Can be used for instance to obtain
permanent minimum heating. Care should be taken since high settings might interfere with the control loop
07: max. output %
(value range 0 to 100)
