The piclient.ini file is used to support buffering configuration and if a pilogin.ini file cannot be found, to define the default PI server. The piclient.ini file (below) indicates that a PI program under Windows will resolve remote PI function calls with the PI Server named MYVMSSERVER by default. Default connections are made if the PI program calls the piut_connect function, calls the function piut_setservernode with a NULL string or function calls made without calling for a connection first. Again, the piclient.ini file is only used for this purpose if the pilogin.ini file cannot be found or older versions of the PI-API are being used.
[PISERVER]
PIHOMENODE=MYVMSSERVER
DSTMISMATCH=0
Typical entries for a piclient.ini file are used to enable buffering and to allow the PI-API client program to correctly adjust time offsets for PI servers and clients using different Daylight Savings time rules. For example:
[PISERVER]
DSTMISMATCH=3600
[APIBUFFER]
BUFFERING=1
