5.3.3 Signal Contact
The signal contact is for
D manual setting the signal contact .
D monitoring proper functioning of the RS2-4R.
U Manual setting
This dialog gives you the option of remote switching the signal contact.
V Select "Opened" in the "Manual setting" field to open the contact.
V Select "Closed" in the "Manual setting" field to close the contact.
Application options:
D Simulation of an error during SPS error monitoring.
D Remote control of a device via SNMP, such as switching on a camera.
U Proper functioning
The signal contact monitors the functions of the RS2-4R which makes it
possible to perform remote diagnostics.
A break in contact is reported via the zero-potential signal contact (relay
contact, closed circuit):
D the failure of at least one of the two supply voltages (power supply
voltage 1 or 2 < 18 V)
. Select "Redundant power supply ignore", if you
have not connected a redundant power supply.
Note: With non-redundant supply of the mains voltage, the RS2-4R re-
ports a power failure. You can prevent this message by applying the
supply voltage over the two inputs.
D a continuous malfunction in the RS2-4R (internal 3.3 VDC voltage).
D the defective link status of at least one port. With the RS2-4R, the in-
dication of link status can be masked by the management for each
port. Link status is not monitored in the delivery condition.
D error during self-test.
The following condition is reported in RM mode:
D Ring monitoring is not possible, e.g. during software initialization.
