Communicating with Devices on a ControlNet Link 7-23

Example 3: Sending MSG Instructions

You configure a MSG instruction to a Logix5550 controller the same as you

do for a DriveLogix controller. All Logix-based controllers follow the same

MSG configuration requirements. See Example 2 above.

Configuring a MSG instruction for a PLC-5 controller depends on the

originating controller.

For MSG instructions originating from the DriveLogix controller to the

ControlNet PLC-5 controller:

The PLC-5 controller supports logical ASCII addressing so you do not have

to map a compatibility file for MSG instructions initiated by a PLC-5

controller. Place the DriveLogix tag name in double quotes (“).

Example 3: Producing and Consuming Tags

You can produce and consume tags with any Logix controller the same as

you do with a DriveLogix controller. All Logix controllers follow the same

requirements for producing and consuming tags. See Example 2 above.

Type of Logix MSG instruction: Source: Destination:

Typed Read any integer element (such as B3:0, T4:0.ACC,

C5:0.ACC, N7:0, etc.)

SINT, INT, or DINT tag

any floating point element (such as F8:0,

PD10:0.SP, etc.)

REAL tag

Typed Write SINT or INT tag any integer element (such as B3:0, T4:0.ACC,

C5:0.ACC, N7:0, etc.)

REAL tag any floating point element (such as F8:0,

PD10:0.SP, etc.)

Word Range Read any data type (such as B3:0, T4:0, C5:0, R6:0,

N7:0, F8:0, etc.)

SINT, INT, DINT, or REAL

Word Range Write SINT, INT, DINT, or REAL any data type (such as B3:0, T4:0, C5:0, R6:0,

N7:0, F8:0, etc.)

Type of MSG Instruction: Example Source and Destination:

PLC-5 writes to DriveLogix source element N7:10

destination tag “array_1”

PLC-5 reads from DriveLogix source tag “array_1”

destination element N7:10
