11.5.1 Take notice
At the PG-software, it may possibly occurs that the COM-port of the PC have wrong entries.
You must show into the COM.INI file and check the parameters and may change them.
Anywhere in that file stands:
; (English)
; Baudrate: speed at which SUCOSOFT S30-...
; sends and receives data. Permissible values:
; 110, 150, 300, 600, 1200, 2400, 4800, 9600 baud
; ReceiveTimeout: Time that must elapse after the receipt
; of a character before the transfer is aborted with
; an error message. The value for this parameter
; must be an integer value entered in seconds.
some lines later:
Baudrate=9600
ReceiveTimeout=1
This values must be the same.
For the connection to a PS4-201, the connection cables must be make by yourself, because the
operation panels often have a 9-pin-connector, but not the rounded DIN-connectors. The
cable must be customised with regarding at the connector assignment of the PG-MUX and the
connector assignment of your operation panel. The connection cable to the PC must be a 9 pol
1:1 cable. The bridges who were needed by the PG-software are connected internally in the
PG-MUX at both PG connectors.
If two operation panels were connected to the PG-MUX, both must be differently configured,
in case of that the operation panels haven’t the same FW´s and DB´s. If the FW´s and DB´s
are the same, the PLC can not distinguish from what OP the data was transferred. That
problem doesn’t appears when you use different FW´s and DB´s.
You should generally enter a `time-out` into your OP (if it is possible), because if a PG
transfers a large DB (for example), the OP must wait for the next conversation with the PLC.
If you increase the time-out, the OP waits for a longer time, can’t go into the ´time-out´. A
good time is 3-5 sec.
