Caution:- PC Power Supply Overload
When using the FX-2PIF with peripherals that draw power from the PC, care should be taken not to overload the PC.
If this happens, the normal operation of part or all of the system will be affected; the worst case being the PC shuts down.
The FX PC can supply 5V DC 290mA, in addition to which is the power required by a programmer (150 mA).
Hence, the total available 5V DC supply from an FX PC is 290 + 150 = 440 mA.
Take care to note the supply required by special function blocks as well. If necessary add an extension unit to power the special blocks.
Points For Use Of The FX-2PIF
1) For FX2N series either FX or FX2N support is possible but all peripherals must also conform to this setting.
When the FX2N setting is used all of the connecting peripherals must fully support FX2N.
Otherwise, set the FX-2PIF for use as for FX and ensure that none of the peripherals are set for FX2N support.
2) The following combinations of PC and FX-2PIF can be used;
