D-9

D Buep 19e-Direct driver

Other:

Timer T1 „TIMER“ is used for timeout monitoring in the PCS_KOMM

program.

INIT

Determines the initialization values of the PCS data area. Here, you

can pre-assign the interlocks for the data transfer. Allow only so much

data exchange as needed. With the exchange of fewer data, the

communica-tion speed is increased.

COFF

Determines the measures at a communication loss. The block is

executed once after a communication loss.

Attention!

Check the functioning of the handling software. The INIT and COFF blocks

must be pre-assigned for the respective PCS. The program listing shows

some examples.

D1.4 Implementation of the software

The README.DOC/PROJECT.DOC files on the PCS 91.BOS floppy disk

contain current notes concerning the use of the various projects.

Procedure:

• Equip the rack

• Set the block address on CPU and I/O boards

• Set the interface on the CPU and the SK (if possible set all to the

same parameters)

• Copy the corresponding project (e.g. BOSMULPS.500) stored on

the PCS 91.BOS floppy disk to the hard disk

• Supply voltage to the programmable controller and the I/O boards

• Run the programmable controller programming software, select the

project for the CPU, enter the configuration in the SK table and transfer

it into SK (under LOADER).

• Transfer the programmable controller program into the controller using

the loader (if necessary, link in your application program and link

newly)

• Connect PCS and programmable controller using an adapter cable

described in section 4 (are the DIL-switch segments 5 and 6 at the

PCS correspon-dingly set?). The location for attaching the adapter

cable is arbitrary. How-ever, the block address must be correct and

the communication baud rate must correspond with the PCS.

Plugging the communications cable into the addressed CPU will

increase the communication speed.
