Communicating with Devices on a ControlNet Link 7-25
The ControlNet PLC-5 controller stores floating-point data, which
requires 32-bits regardless of the type of controller, as follows:
– The first integer contains the upper (left-most) bits of the value.
– The second integer contains the lower (right-most) bits of the value.
To re-construct the floating point data within the ControlNet PLC-5
controller, first reverse the order of the integers and then copy them to a
floating-point file.
Consuming a Tag from a ControlNet PLC-5 Controller
To consume a tag from a ControlNet PLC-5 controller,:
1. In RSNetWorx software, open the ControlNet configuration of the
ControlNet PLC-5 controller, insert a Send Scheduled Message.
2. In RSLogix 5000 software, add the ControlNet PLC-5 controller to the
Controller Organizer.
3. Create a user-defined data type that contains these members:
4. Create a consumed tag with the following properties:
5. In the RSNetWorx for ControlNet software, reschedule (save)
the network.
Data type: Description:
DINT Status
INT[x], where “x” is the output size of the data
from the ControlNet PLC-5 controller. (If you are
consuming only one INT, no dimension is
required.) Data produced by a ControlNet PLC-5 controller
For this tag property: Type or select:
Tag Type Consumed
Controller The ControlNet PLC-5 that is producing the data
Remote Instance The message number from the ControlNet configuration of the
ControlNet PLC-5 controller
RPI A power of two times the NUT of the ControlNet network. For
example, if the NUT is 5ms, select an RPI of 5, 10, 20, 40, etc.
Data Type The user-defined data type that you created.
