DH-485 Interface Converter
For communication, use an RS-232/DH-485 Interface Convertor
(Catalog Number 1747-PIC) between the computer and SLC
controller. The converter includes a 279.4 mm (11 in.) ribbon cable,
already attached to the converter, for connection to the computer
serial port and a Catalog Number 1746-C10 cable for connection to
the controller.
If you are using an SLC 5/03, SLC 5/04, or SLC 5/05 processor, you
do not need the 1747-PIC. You can program via the RS-232 channel
using DF1 full-duplex protocol or DH485 protocol and RS-232
Program Cable (Catalog Number 1747-CP3).
Monitoring with a Data Table Access Module
The Data Table Access Module (DTAM) is a plant floor device that
lets you access data file information, change operating modes,
monitor and clear processor faults, and transfer the user program
between RAM and an EEPROM memory module with any SLC 500
family processor. You cannot use it to create new programs.
Important features of DTAM include:
• shorthand addressing, which provides easier access to data files
• display prompts in six, user-selectable languages: English,
French, German, Italian, Spanish, and Japanese
• UL listed, CSA Certified
• NEMA type 12 and 13 enclosures
• point-to-point interface to an SLC family processor, or as a
network device on a DH-485 network
Monitoring with a DTAM Plus
The DTAM Plus provides a highly functional operator interface for
the SLC 500 family of processors. This device features a 4 line x 20
character display window for viewing data table information and
operator prompts. Display screens are created using an Offline
Development Software Package. Screens can depict register
information, prompt for operator data entry, or facilitate
downloading of recipes, allowing modification of multiple registers
with a single keystroke. Alarm screens monitor critical data table
registers, prompting the operator for action when out-of-range
conditions exist.
