CTI 2572-B / 2500C-2572-B Installation and Operation Manual 26
Configuring the Write Message Block
Configuration Tab
The S
OURCE ELEMENT specifies the Control Logix tag that will contain the data to be written to the 505 PLC. We
defined this tag in the first section. Since this is an array, we will specify that first value to be written is array
element 0. Subsequent elements will be written up to the value specified in the Number of Elements box.
Since we want to write a block of 50 registers, the NUMBER OF ELEMENTS will be set to 50.
The DESTINATION ELEMENT specifies the 505 PLC Tag Name. We want to write 16 bit unsigned integers, so we will
use the tag type VS. Since we want to start reading at V memory location 601, the complete Tag Name is
VS601.
Communication Tab
The communication tab defines the path to the target 2572-B. See the dialog box for Message_1 above.
