4.15 FC 19 – Collective information “Check Position”
This function is for accomplishing the gateway function command „Check Position“.
The command is processed in the same way as previously described. Same restrictions as for block
processing do apply. Latter is not existing and has to be completed if required.
Call function
CALL FC 19
Number_not_in_posi := INT
Time_Out := BOOL
Error := BOOL
Busy := BOOL
4.16 FC 21 – Automatic SPA scanning operation ON or OFF
This function is for switching ON or OFF the automatic SPA scanning operation. The desired option is
entered by aid of a bool variable. For automatic scanning operation ON, enter 1 = TRUE respectively 0
= FALSE for OFF.
Although by this command the gateway default parameter is overwritten it does not mean a permanent
alteration. Some commands require switching off the automatic scanning operation since they are only
valid until another command is received – for example indicate SPA identifier in the lower display or
with any automatic placing of identifiers.
