Idec Plc Fa2j Manual ((better)) Access
IDEC FA2J Series PLC Specification Report (also known as the FA-2 Junior
Programming for the FA-2J can be handled via hand-held hardware or Windows-based software. idec plc fa2j manual
Cables: Programming typically requires the PFA-1A51 communication cable. IDEC FA2J Series PLC Specification Report (also known
The system is built on a modular platform requiring a base plate for expansion. Description Part Number (Examples) CPU Unit Main processing unit (AC or DC models available) PF2J-CPU1E (AC), PF2J-CPU1DCE (DC) Input Modules Options for DC, AC, and 8-bit or 12-bit analog inputs PFJ-N161 (16-pt DC), PFJ-N083 (8-pt AC) Output Modules Relay, transistor (sink/source), and SSR options PFJ-T081 (Relay), PFJ-T082 (Transistor) Base Plate For mounting expansion I/O modules Memory Packs Replaceable plug-in packs for easy program storage PFA-1M21 (1K RAM), PFA-1M14 (4K EEPROM) [Source: 1.2.6] Programming & Software Very clear basics of scan cycle (input read
- Very clear basics of scan cycle (input read → logic solve → output write).
- How to implement a latch (KEEP instruction) and one-shot (DIFU/DIFD).
- Wiring of sinking vs. sourcing DC inputs – applies to any PLC today.
3. Programming Environment (Major Weakness)
Software – Obsolete
- Supported software: IDEC FA Programmer for Windows (16-bit, Windows 95/98/ME) or hand-held programmer (FX-20P-E equivalent).
- Modern OS: Will not install/run on 64-bit Windows. Requires DOSBox, virtual machine (Win98), or vintage PC.
The FA2J series features a space-saving modular design with several key hardware capabilities: Processing Speed: 6ms per 1K basic instructions.
- Then (FA2J): "The instruction MOV moves data from S to D." (Technical definition).
- Now: "How to move data: Use the MOV instruction to copy a value from a source register to a destination register. Example: Use this to set a timer preset value." (Task-based definition).
