Faults in connection with a communication interface
9.3.1
Checking the PC
Check addressing (was the correct device addressed?)
Changing settings of the wrong device can lead to serious damage in the plant! For this
reason, especially after commissioning, it has to be ensured that the correct device is
accessed. For that it is recommended to get a confirmation by phone from a person
standing in front of the device.
Ethernet: read IP-address from SYNCHROTACT 5 (refer to section 7.1.1) and compare
with the selected address in the SynView program of the host system (e.g. PC). If the
IP-address of the device has to be changed, follow section 7.2.2. Possibly check the
connection using the ping command in the "Command Prompt" program. "Command
Prompt" can usually be found in the Windows Start-Menu under Accessories.
Modbus, Profibus, Lon-Bus: check configuration of the related interface according to
section 4.3 and modify if required.
9.3.2
Checking the connection
Check status display of the related communication interface according to section 9.3.5
to 9.3.9. Is the LED or the interface defective? Test: When switching power supply on,
both LED's shall light up at least once alternately.
Check cable connection (contact pins, connector; cable crossed or 1:1?).
9.3.3
Checking the SYNCHROTACT 5 device
Check whether the blocking input (-X1b) is active. The operating interface is blocked
with active blocking input.
Check whether the SYNCHROTACT 5 device works well if the communication interface
is not used. Is SYNCHROTACT 5 in READY, OPERATING or BLOCKED status?
Possibly switch off and on auxiliary voltage and wait for the end of initialization (i.e., till
the alternately flashing Ethernet LED's stop or approx. 10 s).
Possibly replace the device with a spare one, if available.
