Note:
•
Please refer to chapters 3.1.4, 3.2.26, & 5.4 for more information on the digital interface.
•
The digital outputs (pins 1…17) are realized as dry relay contacts, pins 18 and 19 are the common pins
(Out_Common).
If a contact is open, it means that the corresponding module is switched to the primary input port ("
In A
"). If it
is closed (i.e. it has the same electrical potential as the common pins), the module is switched to the
secondary input port ("
In B
"). An exception is pin 17 that indicates the status of module 16 as a normally
closed contact, i.e. contradictory to pin 16.
•
The digital inputs (pins 20…35) are realized with optocouplers with pins 36 & 37 as the common ground pins
(In_Common).
If the device is switched (from Local Mode or Auto Mode) to Remote Mode with Individual switching mode
activated and if no voltage is applied to a digital input, the corresponding module is switched to the primary
input port ("
In A
"). On the other hand, if a positive electrical potential (Option 56: n24 V, 5.8 mA and
Option 57: n12 V, 4.8 mA) is applied to a digital input, the corresponding module is switched to the
secondary input port ("
In B
").
If the device is switched to Remote Mode with Simultaneous switching mode activated, the potential on the
digital input of the first member of a group determines the switch position of the group.
If the device is in Remote Mode and Individual switching mode is activated, a rising slope on a digital input
forces the corresponding module to be switched to the secondary input port ("
In B
"); a falling slope switches
the module to the primary input port ("
In A
").
If the device is in Remote Mode and Simultaneous switching mode is activated, a rising slope on any (!) digital
input assigned to a module being member of a group forces the corresponding group to be switched to the
secondary input port ("
In B
"). A falling slope on any digital input assigned to a member of a group switches the
group to the primary input port ("
In A
").
