I have an issue with one of my two Digital Powerbar6D's (NON PAB).
The unit has been turned off for about 6 months and was working fine before it was turned off, the second unit is working fine.
If I connect the working unit (Powerbar A) to the PIII Ex with FW 5.16 5/06/2013 with PLC 5.1.6.2 the following steps allow me to manually turn on/off sockets 1 to 6.
1. In system, socket functions tick "Digital powerbar connected to S1-S4" then click save
2. with nothing else connected to the system the power light flashes slowly
3. other than the laptop via serial I connect the cable to the powerbar to S1-S4
4. wait for the Com light to come on (orange) and the pwr light to stop flashing
5. in PLC set sockets 1 and 6 to be always on, click save
6. within PLC click on "Program digital powerbar or dosing pump unit..."
7. Select the default choice for numbering
8. Accept the default numbering of 1
9. Click program then ready
For Powerbar A, this all works as expected, sockets S1 and S6 turn on and I can manually control the sockets from plc.
I then disconnect the working powerbar from the cable to the PIII Ex and repete the steps above with powerbar B.
This powerbar does not turn on sockets S1 and S6 and I cannot manually control the sockets from plc
The only change is the powerbar, everything else is exactly the same.
When connected to the PIII Ex the power light on the powerbar stops flashing and the com light stays on orange.
I have tried swapping cables with the same result (Powerbar A works with both cables, Powerbar B does not with either cables).
I have tried swapping ports on Powerbar B
I have tried substituting S5-S8 and using sockets 25 and 30 with the same result
is there anything else that can be done to "reset" the powerbar and make it work, or is this likely to be a failure of the unit?
