3.1.1 Explanations About the Example Programs
MVI693964R_v13.ACD is the general S3964R communication program used for
the following types of 3964R jobs:
3.1.2 The 3964R Communication Program
The general functionality of the program MVI693964R_v13.ACD is as follows:
Send jobs to a CP:
ƒ Transfer the job data to the MVI69-S3964R.
ƒ Acknowledgement from the MVI69-S3964R regarding validity of the job data.
ƒ Depending on the type of send job the transfer of the user data from/to the
MVI69-S3964R/CompactLogix or MicroLogix processor takes place.
ƒ Acknowledgement from the MVI69-S3964R regarding
successful/unsuccessful completion of the send job.
Receive jobs from a CP:
ƒ Depending on the type of receive job the transfer of the user data from/to the
MVI69-S3964R/CompactLogix or MicroLogix processor takes place. The
header data generated from the MVI69-S3964R will be added automatically.
The MVI69-S3964R needs no extra job data from the CompactLogix or
MicroLogix processor for receive jobs, it will be triggered through the STX
character sent from the CP to establish the communication.
ƒ Acknowledgement from the MVI69-S3964R regarding
successful/unsuccessful completion of the receive job.
During the processes described above additional status/error messages may be
transferred from the MVI69-S3964R to the CompactLogix or MicroLogix
processor (refer to Module Status Data Table (page 69)). Refer to Error
Processing for more information.
