C Buep 19e-Expander driver

Connection of the PCS to the PLC 1. Set DIL-switch 8 to „OFF“ and DIL 9 to „ON“ (on the rearside the

PCS). Set the DIL-switches 5 and 6 according to the selected baud

rate and interface. Initiate a reset of the PCS.

2. Apply operating voltage (19..33V) to the PCS. At least the ERR LED

must light now.

3. Connect the programming interface of the programmable controller

to the PCS using a suited cable.

4. Set the P2 restart input to „1“.

5. Now the ERR LED at the PCS must be deactivated. Idle text 0 is

shown on the display of the PCS.

After setting and loading the PLC corresponding to section 2, you can

connect the PCS to the PLC corresponding to the following instructions.

Attention!

Check the function of the PCS and PLC after programming or driver

installation. All parameterized functions have to be checked. Otherwise

failures of the PCS or PLC are possible.

Trouble-shooting Errors which might occur during first commissioning are listed below:

1. DIL switch 8 is set to ON. In this case, the PCS starts a diagnosis

routine after being switched on. This routine is only required for test

purposes. Remedy: Set the DIL switch to OFF and restart the PCS

(by switching it off for a short time or by shortly pressing the RESET

push-button located above the DIL switch).

2. The DIL switches 5 and 6 (interface and baud rate selection) are not

correctly set. Check the settings at the PCS using the HLP key and

arrow-down key.

3. Is the correct cable being used? This is PCS 706 for TTY (observe

the polarity) and LCA 035/235 for RS-232 (polarity not important) or

a cable as described in chapter 3.

4. Has the correct program being loaded into the programmable

controller? Does the P2 parameter indicate a „Restart after fault“?

5. In dataword 3 of the PCS datablock will be reportet an error wiith a

value different to zero. In this case the error should be searched in

the PLC-PCS connection. Possibly the cable is defect.

6. Communication is established but after a certain time the PCS

displays the following message:

======== COMMUNICATION ERROR ========

In this case, please read the following section.
