Configuring the Write Message Block
Configuration Tab
The S
OURCE
E
LEMENT
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 N
UMBER OF
E
LEMENTS
will be set to 50.
The D
ESTINATION
E
LEMENT
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-A. See the dialog box for Message -1
above.
