PCMCIA (E984-

275/285 Only)

The E984-275/285 CPUs support PCMCIA release 2.1 type II socket. The CPU

provides routines for accessing the PCMCIA card. Drivers are included to support

additional memory via AMD compatible memory cards. The card may be used to

store your application or as dynamic storage for data. You may write and read your

applications to either FLASH or PCMCIA card. You may use the PCMCIA card for

data logging from the user program via the DLOG instruction. (See Program Storage

using FLASH RAM & PCMCIA (E984-258/265/275/285 Only), p. 44).

Transferring

MEEP

Applications to

PCMCIA Cards

Applications on earlier models (A984-1xx, E984-24x/251/255) using MEEP cards

can not be directly ported to the newer models (E984-275/285). This occurs

because the PCMCIA card replaces the MEEP card. In this case, go into the

Concept directory and run convert.exe. This converts your Modsoft application files

to Concept project files. Then select your PLC type. However, your I/O map is not

converted because the E984-258/265/275/285 PLCs I/O drivers are different than

the older models. Thus, reenter your I/O map and validate your analog scaling within

your application. The PCMCIA card works in a similar manner as the MEEP in earlier

models.

PLC Login

Password

Protection

(E984-258/265/

275/285 Only)

This feature allows you to prevent unauthorized writes to the PLC via Modbus

commands. The password must be at least 1 character and may be up to 16

characters long. Valid characters are: a ... z, A ... Z, 0 ... 9. Spaces are NOT allowed

and the password is case sensitive. The default is no password. The PLC MUST be

stopped before entering a password. Checking the box labeled PLC level password

protection enables this option. The password is entered in two steps. First you enter

your password into a Concept dialog box to gain access to the PLC. Second, from

the main Concept menu select Online, Online Control Panel, then Set PLC-

Password... The Change PLC-Password dialog box appears. Enter your password.

Then confirm with OK. To deactivate the password feature, enter the old password

and press OK. This prompts a confirm to remove.

The following figure shows the Change PLC Login Password screen.
