Write to SCADAPack 4202 DR Analog Output

Syntax

#include <ctools.h> unsigned isaWrite4202Outputs( int aoutData

)

Description

The isaWrite4202Outputs function writes data to the analog output of the

SCADAPack 4202 DR I/O. aoutData is the analog output value.

The function returns FALSE if an I/O error occurs; otherwise TRUE is returned.

Notes

When this function writes data to the SCADAPack 4202 DS I/O it also processes the transmit buffer for the com3 serial port. The com3 serial port is also continuously processed automatically. The additional service to the com3 receiver caused by this function does not affect the normal automatic operation of com3.

The IO_SYSTEM resource needs to be requested before calling this function.
