B1. First Commisioning

First commissioning

B1.1 Delimitation

The successful parameterization of the PCS as described in the PCSPRO and/or

PCS9092 manual is assumed. This appendix relates exclusively to the use of a

PCS together with an AEG A120/A250 controller. This controller is defined in the

following as programmable controller. The AEG-specific terms and the

programming of the programmable controller with the Dolog AKF software are

assumed as known. The used communication protocol is defined as BKOS protocol.

The enclosed handling software was created for an ALU 202 (A120) and ALU 151

(A250).

B1.2 Loading the AEG 120 DR driver into the PCS

During configuration of the PCS, the application program with data and a selected

driver are both transferred. The driver is called AEG120DR.DRV (AEGBKOPS.DRV

for PCS900). The procedure is the same as described in the PCSPRO/PCS9092

manual.

The following variables for the AEG120DR driver can be set:

 The AA variable and/or COM_TIMEOUT: PCS time-out time

The time-out time determines the maximum admissible time for the processing

of the synchronization word in the programmable controller. As default, this

time is 400 for AA. This corresponds to 4000 ms = 4 seconds. Admissible values

for the AA variable are from 200 to 999 (= 2 to 9.9 sec.). The AA time-out time is

only activated with the SYNC AND TIME-OUT setting.

 The AC, AD, AE, AF variables and/or COM_MODE: Synchronization

DIL switches 5 and 6 and/or the rotary switch on the rearside of the PCS can be

set to 2 values:

 NO SYNC, NO TIME-OUT ; 2) SYNC AND TIME-OUT .

With SYNC, the usage of a synchronization word is mandatory. NO SYNC

uses no synchronization word. TIME-OUT requires the usage of a time-out

timer (with respect to the time specified in the AA variable). NO TIME-OUT

prevents a time monitoring of the communication in the PCS.

 The AL variable and/or COM_DAT_STR: START ADDRESS WORD.

Determines the first used flag word in the programmable controller. Thereby,

the variable has an offset function. The possible values for flag words are 1 to

1956. Default setting is 100. Therefore, the flag word is 100. Thus, the PCS word

0 is assigned to flag word 100.

 The AT variable and/or CPM_DAT_END: END ADDRESS WORD.

Determines the last used flag word in the programmable controller. The possible

values are from 30 to 1985. Default value is 355. This variable influences the

word area to be used in PCSPRO.

Thus, the used area is AM-AL+1 = x words in size. E.g. for AM = 355 and AL =

100 the flag area is 256 words.

 The AJ variable and/or COM_MAXLEN: Maximum number of packages per

communication cycle.

In a communication cycle, the PCS forms sub-packages for each task. The

number of these sub-packages can be limited. This results in reducing the time

for a communication cycle. This can be advantageous for fast jog operations

(as far as possible without variable display). On the other hand, the refreshing

of variables thereby takes longer. Limit this variable only if all other measures

have not resulted in sufficient time savings. The possible values are between 1

and 50. Default value is 50.
