Service Request
Note The sample program above always reads 10 words (20 bytes) of data. The
Unit records the number of bytes of data that were actually read in allocated
CIO area word n+6.
This program sends a service request (SRQ message) to the Controller.
The Controller performs serial polling and the Unit’s status byte is sent during
this serial polling from the Controller.
When W000.00 is turned ON, the SRQ Request Bit (CIO 2000.14) is turned
ON and an SRQ message is sent to the Controller.
The SRQ Received Flag (CIO 2007.12) will go from ON to OFF when the sta-
tus byte transmission is completed, so this flag can be used to detect the
transfer of the status byte.
Before turning on the SRQ Request Bit, write the status byte data (bits CIO
2000.08 to CIO 2000.13 and CIO 2000.15) that will be sent during serial poll-
ing.
Sends the Unit’s internal status to the host computer. The following diagram
shows the functions of the signals in the status byte.
BIN:
P.ERR: When this bit is “1”, it indicates that a parameter error has occurred.
C.ERR: When this bit is “1”, it indicates that a command error has occurred.
T.ERR: When this bit is “1”, it indicates that a timeout error has occurred.
G.ERR: When this bit is “1”, it indicates that a GP-IB interface error has
