Compatibility of FP2SH and FP2, and Precautions

Hardware Compatibility

Most of the units and related products used with the FP2SH can be used with the FP2, but the following differences should be noted.

Some optional memory units cannot be used.

  • The only memory unit that can be used with the FP2SH CPU FP2-C2 or "FP2-C2L" is the "Part number FP2-M7 or Model number AFP2208".
  • The FP2 memory units "Part numbers FP2-M1, FP2-M2, FP2-M3, and FP2-M6" cannot be used.

The types of optional ROMs are different.

  • The only ROM that can be used with the FP2SH CPU unit "FP2-C2" is the "Model number AFP5208 or AFP5209". The nonvolatile memory implemented memory unit "Model number AFP2208" can be also used.
  • The FP2 ROM "Part number AFP2204" and "art number AFP2205" cannot be used.

The backup battery types are different.

  • The backup battery for the FP2SH CPU is the "Part number AFP8801" battery with a connector.
  • The "Part number AFC8801" battery for the FP2 CPU cannot be used.

The calendar timer and comment memories have been installed in advance.

  • These have already been installed in the FP2SH CPU, and no optional units are needed.

ROM operation functions in the FP2SH

  • CPUs that support IC memory cards (FP2-C2P and FP2-C3P) have an internal FROM used as a program memory. The internal FROM cannot be replaced.

Software Compatibility

The FP2SH has a higher level of compatibility than the FP2, so there are no functions that cannot be used with the FP2SH.
Other factors, such as the number of device points, should be confirmed by checking the specifications comparison table on the previous page.

Compatibility of FP2/FP2SH and FP10SH, and Precautions

Hardware Compatibility

The unit, backplane, and other components are not compatible.

  • The components for the FP2 are used with the FP2SH.

When using the FP2 backplane (AFP25**), the maximum number of expansion points is lower.

  • With the FP10SH and FP2 backplane H type (AFP25**H), up to three expansion boards can be used, and a maximum of 2048 points controlled, but if using the FP2 backplane with the FP2/FP2SH, only one expansion board can be used, and a maximum of 1600 points controlled.

Different types of IC memory cards are used.

  • The only type of IC card that can be used with the “Part number FP2-C2P and FP2-C3P” FP2SH CPU is the IC memory card (small PC card). The IC memory card for the FP10SH cannot be used.

Software Compatibility

With the FP2SH, in comparison with the FP10SH, there are no functions that cannot be used. For other detailed specifications, check the specifications comparison table on the previous page.

IC memory cards for the FP2SH

The existing model number becomes the one to be discontinued because of the termination of manufacturing IC memory cards by the parts manufacturer. When placing a new order, specify the new product number.

Termination of Production

Type Memory capacity Model No. Battery type
SRAM 2MB AIC52000 Internal secondary battery (Rechargeable type)

New product

Type Memory capacity Model No. Battery type
SRAM 2MB AFP2209 Lithium Battery (Interchangeable type)

Notes

For AFP2209

  • An interchangeable lithium battery is used. When you use for the first time, install the battery included.

For AIC52000

  • Memory backup of the SRAM type of IC memory card (AIC52000) Is handled by an internal secondary battery. When the battery is used for the first time, power must be supplied for at least 24 hours to charge it fully. When the battery is fully charged, data is backed up for more than three months with out the power being turned on. Normally, the card should be installed in the PLC and power supplied when using it. Failing to charge the battery periodically can reduce the backup period and the service life of the battery. The backup battery cannot be replaced.
