S4500 PLC
The S4500 is a fourth-generation Micro-Comm RTU/PLC built on the S4000 motherboard
utilizing a new daughterboard with a faster 32bit microprocessor and more RAM and FLASH
memory. As a result, the S4500 software has the following enhanced features:
I/O capabilities:
(8) Relay outputs with conrmation read-back inputs
(8) Open-collector outputs
(16) Discrete inputs (contact closure) / low speed pulse inputs (up to 50Hz)
(8) 12-bit analog inputs (0-20mA or 0-5volt dip switch selectable)
(8) additional 12-bit analog inputs
(4) 0-5volt analogs AI9-AI12 on the terminal blocks
(4) internal signals: RTU temperature (0.25 to 4.75v = -50C to +150C = -58F to +302F),
Battery Voltage (0 to 5v = 0 to 25.5 volts from battery),
Battery Current (0 to 5v = -10 to +10 amps from battery) plus an input on COM1 25pin port
(2) Pulse inputs - high speed (2.5kHz/500Hz)
(2) RS-232 communication ports
- COM1 is the radio (COM1B=9pin monitor port, COM1A=25pin for radio cable)
- COM2 is a 9pin port normally used for the display module and programming
(1) RS-485 communication port
- COM3 is a 4-wire RS-485 port for I/O modules or for PLC communication
(12) Address input switches
Changes and Enhanced Features:
• Setup requires the newer “RTU Conguration 32” program
• New data table and user memory viewing options in RTU Conguration 32
• New Micro-Comm RTU32 protocol
• New personality module required with 1MB of serial ash (yellow label)
• User Memory is now 9000 words of non-volatile RAM
• User NV Memory is now 65000 words of personality module FLASH
• User Memory screens added to Micro-Comm display module for custom variables/parameters
• Much larger communication buers for relaying and programming
• Additional protocols on all COM ports (DF1 Half-Duplex Master, DF1 Full-Duplex, Modbus/TCP etc.)
• Modbus and DF1 Half-Duplex Store & Forward (SFTABLE function) on COM1
• PID for up to 16 analog outputs can now all be running at the same time
• Increased maximum script and subroutine size (16KB for main, 2KB for each subroutine)
• Added more subroutines SUB5()-SUB20() and increased # of parameters to 16 (L1-L16)
• Additional pulse inputs (50Hz max) using DI1-DI16 are now available - PI3-PI18
• New script variables for runtimes and cycle counts for DI1-DI16 and DO1-DO8
• Added the RESPOND() script function that can dene up to 128 more addresses
• Added the LISTEN() script function that can listen to up to 128 other RTU replies and save the data
• New script functions: TOTALIZE(),MCOPY(),MFILL(),MAVG(),OSR(),PITOAI(), XCOPY()
• SCALE() function no longer changes the given variable, it just returns the scaled value
• New script variables M0-M8999 to make access to user memory locations much easier
• Added the GROUP() and CGLEVEL() functions to dene and automate control groups for SCADAview 32
• New CTU32 protocol option on COM2 and COM3 for use with SCADAview 32
• Added COM2 baud rate and PTT time options for data radio support
• DF1 Radio Modem protocol for all COM ports along with Store & Forward option on COM1
• Revision notes / commented script can now be stored in the personality module (up to 64K bytes)
• A compressed PC le can now be stored in the personality module (up to 256K bytes)
