ƒ Depending on the type of receive job the transfer of the user data from/to the MVI46-3964R/SLC processor takes place. The header data generated from the MVI46-3964R will be added automatically. The MVI46-3964R needs no extra job data from the SLC processor for receive jobs, it will be triggered through the STX character sent from the CP to establish the communication. 

ƒ Acknowledgement from the MVI46-3964R regarding successful/unsuccessful completion of the receive job.MainRoutine The MainRoutine recognizes the presence of special command request and response messages, and data transfer between the module and the processor.

Transfer Routine

 The Data Transfer task is responsible for handling the transfer of data between the processor user defined files and the module's M1 file. In this example, 30 words of Status Data is read from the M1 file and stored in 3964R0.

Word 0 of the M0 file is used by the module to indicate a response to a special command instruction. During normal program execution, this register should have a value of 0. If any other value is present, the data transfer function will not be executed. The following rung executes the data transfer function (Trnsf U:3) when the control word is set to zero.

9998 Warm Boot

 The SLC processor can request a warm boot operation of the module by placing a value of 9998 is the M1 register 6800 (Command Control Register). Ladder logic to perform this task is shown in the following rung:The SLC processor can request a cold boot operation by the module by placing a value of 9999 in the M1 register 6800 (Command Control Register). Ladder logic The following rung builds a block of data with a header to send to the module. The header data resides in N12 and the message data in N11. The next rung transfers the remaining data to the module This rung shows a data block comprised of a header from N13 and 50 words of data from N19. If more data is to be transferred, an additional rung similar to rung 003 must be added.
