Functions
Optocoupler
3rd party
Figure 24: Connector switch output
Suitable optocouplers ideally have a nominal switch value of 3 V or 5 V and a switching current
below 5 mA (e.g. Phoenix Contact PLC-BSC-5DC/1/ACT (Art.-No. 2980241) equipped with 5
V / 24 V Optocoupler (Art.-No. 2967989).
Set the output signals of the interface Console0 into a defined state for the telecontrol mode
with the commands <set interface console0 dcd off> or <set interface console0 dcd on> for a
deterministic state after booting of the EDS500 device.
If the DCD contact of the interface Console0 is used as feeding supply then it can be switched
on by the command <set interface console0 dcd on> and switched off with command <set
interface console0 dcd off>.
If the command is not applied then the state of DCD depends on the sent data at interface
Console0. In normal operation data can also be sent spontaneously over the interface.
The level of the interface signals DCD and CTS is in the negative voltage area in the state
off.
The information object for input RTS of interface Console0 can be operated in the following
modes:
Mode
switch
on-counter
transition-counter

Concept of Interface and Polling

The IEC 60870-5-101 / IEC 60870-5-104 implementation on the EDS500 devices supports
connections by several telecontrol central offices. You have to distinguish between
independent central offices and central offices that depend on each other.

Description
Switch, returns ON/OFF (ASDU data type 1)
A change triggers spontaneous message.
On-counter, returns counter (ASDU data type 15)
Increment at each transition from Off to On.
Transition counter, returns counter (ASDU data type 15)
Increment at each transition.
