The PC Card Units allows you to expand PC capabilities by adding a PC card.
The PC card can be used to save and retrieve CIO, DM, EM, and other data area
contents between the CPU Unit and the PC card from the ladder-diagram pro-
gram (using the CMCR instruction). An Ethernet card can also be used to con-
nect to an Ethernet network so that data area or ladder-diagram program con-
tents can be read or written from computers on the network. Examples of PC
Card Unit Applications are shown below.

• Program data read via a PC Card Unit cannot be edited on the Ladder Support
Software.
• PCMCIA2.1 PC cards are used (except for 3.3V cards). Two PC card interface
slots are provided. Up to two type I or type II cards can be mounted, or one type
III card can be mounted, enabling applications of standard SRAM, ATA, flash
memory, and other PC cards.
• A Communications Board (C200HW-COM01/COM04-EV1) and a Bus Con-
nection Unit (C200HW-CE001/CE002/CE012) are required to mount a PC
Card Unit to a C200HX/HG/HE PC.
