Description

.PLC (Programmable Logic Controller) module basic information
Make and Model: Allen-Bradley 1746-BAS-T
Purpose: For SLC 500 system, as a high-speed basic language module, to achieve machine-level data collection and integration.
Country of Origin: USA
Warranty: One year (usually provided by the supplier)
Functional characteristics
High-speed performance:
The 1746-BAS-T module has a higher operating speed than the 1746-BAS module, and existing programs written for the 1746-BAS module may need to be adjusted to take advantage of the faster speed to perform the same operation.
Hardware features:
Memory module: Use a different (optional) memory module, such as the 1771-DBMEM1 or -DBMEM2 memory module socket, for non-volatile storage of user programs.
Clock/Calendar: Battery powered 24-hour clock/calendar with a free running clock resolution of 5 ms.
Communication interface:
PRT1 and PRT2: Two isolated 9-pin type D serial ports that support RS-232/423, RS-422, and RS-485 communication. The PRT2 port can also provide DF1 full duplex or half duplex slave station protocols for SCADA applications.
DH485: An RJ-45 port that communicates over the DH485 network.
LED indicators: Multiple LED indicators for the operator interface.
SLC 500 backplane interface: Supports data read and write on the SLC 500 backplane.
Software functions:
Programming environment: Support for BASIC programming using Intel BASIC-52 language and enhancements.
Data processing: Support string operations, floating point operations and conversions, extensive call libraries, etc.
Network support: Supports DH485 network and DF1 protocol.
Other features:
Flexible data storage options: Provides a variety of data storage solutions to meet different application requirements.
Integrated program debugging environment: easy for users to develop and debug programs.
Operator interface function: Provide user-friendly operation interface, easy for operators to monitor and control.
Application field
A-B 1746-BAS-T control module is widely used in many industrial fields, including but not limited to CNC machinery, metallurgy, oil and gas, petrochemical, chemical, paper printing, textile printing and dyeing, machinery, electronic manufacturing, automobile manufacturing, plastic machinery, electric power, water conservancy, water treatment/environmental protection, municipal engineering, boiler heating, energy, transmission and distribution, etc.
