Data contained in this database is paged through the input and output images by

coordination of the ControlLogix ladder logic and the MVI56E-MNETCR module's

program. Up to 40 words of data can be transferred from the module to the

processor at a time. Up to 40 words of data can be transferred from the

processor to the module. Each image has a defined structure depending on the

data content and the function of the data transfer. The module uses the following

block numbers:

Block Range Descriptions

-1 Null block

0 Null block

1 to 125 Read or write data

1000 to 1124 Output Initialization Blocks

2000 to 2029 Event Command Block (page 103)

3000 to 3029 Client status request/response blocks (page 105)

5001 to 5016 Command Control (page 106, page 102)

9990 Set new module IP address (page 107)

9991 Get module IP address

9998 Warm-boot control block (page 109)

9999 Cold-boot control block

These block identification codes can be broken down into a few groups: Normal

data transfer blocks (-1 to 125), Initialization blocks (1000 to 1124), and

Command control blocks (2000, 5000 to 5016, 9998 and 9999).
