Typed Write
Word Range Read
Word Range Write
Type of MSG Instruction:
PLC-5 writes to DriveLogix
PLC-5 reads from DriveLogix
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:
Source:
any integer element (such as B3:0, T4:0.ACC,
C5:0.ACC, N7:0, etc.)
any floating point element (such as F8:0,
PD10:0.SP, etc.)
SINT or INT tag
REAL tag
any data type (such as B3:0, T4:0, C5:0, R6:0,
N7:0, F8:0, etc.)
SINT, INT, DINT, or REAL
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 Source and Destination:
source element N7:10
destination tag "array_1"
source tag "array_1"
destination element N7:10
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.
Communicating with Devices on an ControlNet Link
Destination:
SINT, INT, or DINT tag
REAL tag
any integer element (such as B3:0, T4:0.ACC,
C5:0.ACC, N7:0, etc.)
any floating point element (such as F8:0,
PD10:0.SP, etc.)
SINT, INT, DINT, or REAL
any data type (such as B3:0, T4:0, C5:0, R6:0,
N7:0, F8:0, etc.)
