Setting Up Your Equipment
1–8
Use the Hand–Held Terminal to configure the SLC 500 controller,
enter/modify a user program, download/upload programs, monitor controller
operation, test, and troubleshoot. The HHT has its own memory to store a
program.
You can use the HHT stand alone (for remote programming development
with 1747–NP1 or NP2 power supply), point–to–point (one HHT to one
controller), or on a DH–485 network (communicate with up to 31 nodes over
4,000 feet). When equipped with a battery (1747–BA), the HHT will retain a
user program in memory for storage and later use.
The HHT is menu–driven. The display area accommodates 8 lines x 40
characters. You can display five rungs of a user program. When monitoring
the program in the RUN mode, instructions in a ladder diagram are
intensified to indicate “true” status.
