Installation Manuals

The PLC5 and SLC500 families are the ones to consider. The PLC2 and PLC3 are too ancient (pre-1985), getting the correct software is problematic.

BTW, don't confuse the PLC (5/15, 5/20, 5/40, etc) with the SLC (5/02, 5/03, 5/04, etc) families. Despite the similarity in numbers they're actually totally separate creatures, and use different programming packages to configure.

PLC5 Processors HERE
SLC 500 Processors HERE
   The SLC500 (Pronounced "Slick500")are smaller, maybe about 1/4 the size as shown in the link below. Unless you already have piles of PLC5 pieces/parts to play with, I'd go with the SLC5/04 for a home project.

1747-L54x Processor Card, Front

   The standard DH-485 port has been replaced with a DH+™ port, providing high-speed SLC 5/04-to-SLC 5/04 communications and direct connection to PLC-5 controllers. Modular I/O systems can be configured with a maximum of 3 chassis (30 total slots) and from 4 I/O points to a maximum of 4096 I/O points. The available memory options are 16K, 32K, or 64K. In addition, there is an SLC 5/04P option, which is designed specifically for the Plastics Industry and contains ERC2 algorithms for Plastics Machinery Control.

Keyswitch
   The -L54x processors include a 3-position keyswitch that lets you select a mode of operation: RUN, PROGram, and REMote. You can remove the key in each of the three positions.

WARNING!   Depending on the size of your user program, the processor can take up to 2.5 seconds to change modes when you change the position of the keyswitch from RUN to PROG or to REM. Do not use the keyswitch in place of a hardwired master control relay or an emergency-stop switch.

RUN Position
   Places the cpu in the Run mode. The cpu scans/executes the ladder program, monitors input devices, energizes output devices, and acts on enabled I/O forces. You can only change
the processor mode by changing the keyswitch position. You cannot perform online program editing.
   To change the processor mode to Run, toggle the keyswitch from PROG or REM to RUN. When the keyswitch is left in the RUN position, you cannot use a programmer/operator interface device to change the processor mode.

PROG Position
   This places the cpu in the Program mode. The processor does not scan/execute the ladder program, and the controller outputs are de-energized. You can perform online program editing. You can only change the processor mode by changing the keyswitch position.
   To change the processor mode to Program, toggle the keyswitch from REM or RUN to PROG. When the keyswitch is left in the PROG position, you cannot use a programmer/operator interface device to change the processor mode.

REM Position
   This places the processor in the Remote mode: either the REMote Run, REMote Program, or REMote Test mode. You can change the processor mode by changing the keyswitch position or by changing the mode from a programmer/operator interface device. You can perform online program editing in this position.
   To change the processor mode to REM, toggle the keyswitch from RUN or PROG to REM. When the keyswitch is in the REM position, you can use a programmer/operator interface device to change the processor mode.

Restore Factory Defaults
NOTE: This is only recommendeded if the communication channels have been shut down due to the configuration parameters, or if you absolutely cannot establish communications with the processor.
WARNING! If you return the processor to the initial factory conditions, the user program is lost and communication configurations are returned to their default settings.

1. Remove power from the SLC 500 power supply.
2. Remove the processor from the chassis.
3. Disconnect the battery by removing the battery connector from its socket.
4. Locate the VBB and GND connections on the right side of the motherboard.
5. Place a small bladed screwdriver across the VBB and GND connections and hold for 60 seconds. This returns the processor to the initial factory conditions.

EEPROMS for the 1746BAS and BAST modules
The proms the 1746-BAS and 1746-BAST modules use are listed below.
1746-BAS proms are the 1747- M1 - M2 - M3 - M4.
a) The M1 - M3 are 8K bytes memory.
b) The M2 - M4 are 32K bytes memory.
c) The M1 - M2 are EEPROM.
d) The M3 - M4 are UVPROM.
Note: The BAS module cannot burn/program these. Requires uvprom programming equipment.

1746-BAST proms are the 1771 - DBMEM1 and 1771 - DBMEM2.
a) The 1771- DBMEM1 is 8K bytes.
b) The 1771-DBMEM2 is 32k bytes.
Note: 1747-M11 - M12 ARE NOT USEABLE with 1746-BAS or 1746-BAST modules.
> The 1747 M11 is a 32K "FLASH EPROM" for 5/03 - 5/04.
> The 1747 M12 is a 64K "FLASH EPROM" for 5/03 - 5/04.

Adapter Sockets
Adapter sockets are required when using commercial PROM programmers to program and erase memory modules. The memory module fits into the adapter socket, and then the adapter socket fits into the zero insertion force (ZIF) socket on the PROM burner.
