GPIB-488 4-27 Programming Reference Manual

TestSys

Activate self-test procedures of specified devices.

Syntax

C SendSetup(int board, short addresslist [],

short resultlist[])

Parameters

board is an integer which identifies the GPIB board to use for this operation. In most

applications, this value is 0.

addresslist is an array of GPIB addresses, terminated by the value NOADDR. These

addresses identify the devices to perform self-tests.

Returns

resultlist is an array which contains the results of each device's self-test procedure.

According to the IEEE-488.2 standard, a result code of 0 indicates the device passed its test.

Any other value indicates an error.

ibcnt will contain the number of devices which failed their tests.

ibsta will contain a 16-bit status word as described in Appendix B, IBSTA.

iberr will contain an error code, if an error occurred.

Usage Notes

When this routine is executed, all of the devices identified within the addresslist array are

concurrently sent a message which directs them to perform their self-test procedures. Each

device returns an integer code indicating the results of its tests. This code is placed into the

corresponding element of the

resultlist array.

Example

This example tells the devices at addresses 6 and 7 (from Board 0) to perform thier self-test

procedures.

C short addresslist[3] = {6, 7, NOADDR};

short resultlist[2];

TestSys(0, addresslist, resultlist);

1 2 ... 90 91 92 93 94 95 96 97 98 99 100 ... 115 116
