3.9 Hints for setting up control programs
ITC500 / page 99
NOTE
During the test phase of control programs all program messages should
be transmitted separately. Each command should be followed by a status
request (response message) so that possible errors are read out directly
after the command causing them.
NOTE
The producer of the interface card of the control computer will provide
communication functions for both directions between PC and ITC5xx for all
common software packages. These will be embedded into the
programming text and accomplish the data transfer between control
computer and ITC5xx. We recommend to build these write and read back
commands into separate functions and then use these functions for the
data transfer.
In these functions a globally set flag should be requested that would
determine whether the write or read back communication is to be read out
together with talker and listener address at IEEE488 systems additionally
into a data file or on the printer. When communication problems should
occur at the bus, or in case of error messages that cannot be explained,
the evaluation of the data transfer between the ITC5xx and the control
computer will then be possible without much effort.
