Functions

The CSE 925 is a single slot programmable controller
CPU which provides State Logic control programming
and floating point calculations. The CSE 925 can be
programmed in State Logic, Relay Ladder Logic, and
C to perform real-time control of machines, processes,
and material handling systems.

The AD641 software products are used to program
the CSE 925 in State Logic; the IC641 (MS-DOS) soft­ware products are used to program in Relay Ladder
Logic and C. The IC641 (MS-D OS) software is also
used to perform all configuration functions for the
CSE 925.

The CSE 925 communicates with I/O and smart op­tion modules over the rack mounted backplane
(IC697CHS750, 782, 783, 790, 791) by way of the VME
C.1 Standard format.

Supported option modules include IC697 LAN Interface
modules, Programmable Coprocessor, Alphanumeric
Display Coprocessor, Bus Controller for IC660/IC661 I/O
products, Communications modules, I/O Link Int er face,

1 Mbyte Memory, State Logic

and all of the IC697 family of discrete and analog I/O
modules.

User Me mor y

Program and data memory for the CSE 925 is provided by
a memory board with 1 Mbyte of battery-backed CMOS
RAM. This me mor y board is an inte gral part of th e C SE
925 module and does not need to be ordered separately.

Operation, Protection, and Modul e Sta t us

Operation of this module can be controlled by the
three-position RUN/STOP switch or remotely by an
attached programmer, and AD641 or IC641 (MS-DOS)
software. Program and configur ati on data can be lock ed
through software passwords or manually by the memory
protect keyswitch. When the key is in the protected
position, program and configuration data cannot be
changed. The status of a CPU is indicated by the four
green LEDs on the fron t of the mo dule.

The CSE 925 requires forced air cooling for proper
operation in ambient temperatures greater than 40_C
(104_F). A fan capable of 70 CFM (incl uding filters) should
be located beneath sl ot 1 of the rack containing the CPU.

Fan assembli es (IC697ACC 721 and IC 697ACC724) can be
ordered for direct mounting on the IC697 rack. Refer to
th e ap plica ble Programmable Controller Installation Manual
for detailed information.

Installation

It is the responsibility of the OEM, system integrator , or
end user to properly install the PLC equipment for safe
and reliable oper a t ion. Produc t m a nuals p rovi de
deta iled informat ion abou t i n stallati o n, start u p, and
proper use of the PLC equipment. The installation
manual, shipped with your PLC programming software,
describes how to properly install the equipment. If the
PLC install ati on must comply with supported standards,
such as FCC or CE Di rectiv es, please refer to the
Installation Requirements for Conformance to Standards,
shipped with the PLC programming software, for
additional guidelines.

D

Installation should not be attempted without refer­ring to the applicable Programmable Controller Installa-
tion Manual.

D

Connect the battery to either of the battery connec­tors on the module (see Figure 1).

D

Put the toggle switch in the STOP position.

D

Put the keyswitch in the Memory Protection OFF
position.

D

Make sure that rack power is off.

D

Install the CSE 925 module in slot 1 of rack 0 (see
Figure 2).

D

Turn on power.

The module sho uld power up and the top LED should
blink. When the diagnostics have completed successful ly,
the top LED stays on and the second and third LEDs are
off. The fo urth LED is off if the ke yswitch is in the OFF
position. The CPU is now ready to be programmed.

A fter the program has been verifi ed the toggle switch may
be move d to the appropriate operation mode position.
The LEDs indicate the position of the toggle switch,
memory protection status, and the state of the program.

The IC641 (MS-DOS) software is also used to load the State
Logic operating system into the CSE 925 CPU module.
The ope rating system is provided on a floppy disk with
the CSE 925. The operating system is stored in flash
memory on the module. For information on loading the
operating system, see the State Logic Control System User’s

Manual.

Serial Port

The 15-pin D-connector provides the connection to an
RS-485 compatible serial port on the CPU as shown in
Figure 2.

The serial connection is made from the serial port on th e
CPU to the serial port on the programming computer , or
other serial device, through the RS-422/RS-485 to
RS-232 Converter (IC690ACC900) or RS-232 to RS-422
Miniconverter (IC690ACC901). This connection can be
made with available cables or you may build cables to fit
the needs of your particular application. See reference
3 for more information on serial communications.

Configuration

The IC697 CPU and I/O system is configured with IC641

(MS-DOS) programming software. There are no DIP

switches or jumpers used to configure the system. The
CPU verifies the actual module and rack configuration
at power-up and periodically during operation. The
actual configuration must be the same as the
programmed configuration. Deviations are reported to
the CPU alarm processor function for configured fault
response. Consult Reference 1 for a description of
configuration functions.

Batteries

A lithium battery (IC697ACC701) is installed as shown
in Figure 1. This battery maintains program and data
memory when power is removed and operates the
calendar clock. Be sure to install the new battery before
removing the old battery. Specific indication of a low
battery state is detailed in Reference 2.

Removing a Module

The instructions below should be followed when
removing a module from its slot in a rack.

D

Grasp the board fir mly at the top and bottom of
the board cover with your thumbs on the front of
the cover and your fingers on the plastic clips on
the back of the cover.

D

Squeeze the rack clips on the back of the cover
with your fingers to disengage the clip from the
rack rail and pull the board firmly to remove it
from the backplane connector.
