5.1.4 Functional
Specifications
The MVI46-3964R and the SLC processor communicate via M0 and M1 files
Single-slot, SLC backplane compatible
Multiple modules can be placed in a rack up to the chassis power supply limit
While in 3964R with RK512 mode on PRT1 and PRT2, DB-SEND and DB-
FETCH instructions can be initiated from the SLC processor or received by
the communications partner
While in 3964R without RK512 mode on PRT1 and PRT2, data can be sent
from the SLC processor or be received from the communications partner
The maximum transfer rate is 512 bytes in any mode
Data byte swapping can be configured to adjust to a different word format
While in 3964R with RK512 mode on PRT1 and PRT2, evaluation of the
header information DB (data block), DW (data word) and coordination bytes 9
and 10 is possible
Communication activity and diagnostics are available through LEDs and
acknowledgment telegrams
Ladder Logic
Ladder logic programming in the SLC processor is required in order to enable
and support the Siemens 3964R protocol functionality. The ladder program
handles the encoding/decoding of data transferred from the module as well as
the initiation of protocol-specific functionality in the module. Example ladder
programs are provided with the module to ease the implementation of the module
in the user application.
