Normal Backplane Operation

The MVI56-PDPMV1 module’s application code initiates the data transfers at the

end of every ControlLogix PLC ladder scan. As such, the MVI56-PDPMV1

module is able to actively read and write the PROFIBUS Cyclic Input/Output data

blocks in the appropriate locations.

Input Data Block (Block ID = 1 to 4)

This block contains the previous input data received from the slaves.

Input Data Block Format (Input Image) (Local:1:I.Data Controller Tag)

You can find the contents of the Input Data Block (Input Image) in the

Local:1:I.Data user controller tags in RSLogix.

Word Offset

Start End Name Description

0 199 PROFIBUS Input Data Data received from the PROFIBUS slave devices on the

network.

Total size of the PROFIBUS Input Data block is a function of the

PROFIBUS network configuration.

Block ID 1 = Slave bytes 0 to 399

Block ID 2 = Slave bytes 400 to 799

Block ID 3 = Slave bytes 800 to 1199

Block ID 4 = Slave bytes 1200 to 1535

200 200 Last out mailbox

message ID processed

from output image

The module confirms the receipt of a mailbox by copying its ID

code (Message ID) to this register.

201 201 Current in mailbox

control index

Incremented after the module has transferred a new mailbox

response to the processor.

202 202 Current alarm control

index

Incremented after the module has transferred a new alarm to

the processor.

Input Block Status Data Details (Block ID = 0 to -1)

The MVI56-PDPMV1 module periodically transfers a status block to the

ControlLogix containing relevant information about the module operation (Block

IDs 0 to -1).

The types of data returned in the PROFIBUS Input Status area include:

1 2 ... 226 227 228 229 230 231 232 233 234 235 236 ... 254 255
