We developed the STT Subroutine so that you can easily use a PLC-5
processor to communicate with a HART field device. Here’s how easy it is
to use STT:
1. Install the STT subroutine into your workstation and PLC-5
processor.

2. Customize your PLC-5 ladder logic to use the STT subroutine.
a. Allocate data blocks in your PLCĆ5 processor
for each HART field device in your system.
b. Enter a JSR instruction in your ladder logic
program for each 1770ĆHT1 in your system.
When you’ve completed these steps, you’re ready to use the STT
subroutine.
Go to chapter 2 to begin installing the Smart Transmitter Toolkit.
