Troubleshooting IC693CPU364

Troubleshooting information is available on IC693CPU364's website page; it also includes a datasheet user-manual and a wiring diagram.


Repair your IC693CPU364

PDF Supply can repair your IC693CPU364 in 3-5 business days. And PDF Supply stands by all of its repairs with a 1 year customer satisfaction warranty.


Port 1 on the IC693CPU364 is for Station Manager Use Only


Port 1 (RJ-11) on the front faceplate of the CPU364 is usually labeled RS-232. This port, however, cannot be used for programming, or for data acquisition.


Its only functionality is to use the Station Manager to configure or troubleshoot the Ethernet daughterboard.
The only serial port available for the CPU364 is the 15 pin RS-422/485 port on the power supply.


Troubleshooting Ethernet Communications with Station Manager Software Tool


Station Manager software, which resides in the firmware of the PLC Ethernet Interface products listed below

  • Series 90-30 PLC Ethernet Interface (IC693CMM321), both types.
  • Series 90-30 PLC CPU364 with embedded Ethernet Interface (IC693CPU364)
  • Series 90-30 PLC CPU374 with embedded Ethernet Interface (IC693CPU374)
  • Series 90-70 PLC Ethernet Interface (Type 2) (IC697CMM742)


The Ethernet Interface enables Series 90 PLCs to communicate with other Series 90 PLCs, with GE programming software, and with computer applications developed using GE Ethernet protocols, such as CIMPLICITY- HMI. Refer to GFK-1541, TCP/IP Ethernet Communications for the Series 90 PLC User's Manual for information on installing and programming the Ethernet Interface.

  • Station Manager is a part of the communications software built into the Ethernet Interface.
  • Station Manager executes as a background function to provide interactive supervisory access to the Ethernet Interface.
  • Station Manager is available when the Ethernet Interface is in the Operational or Maintenance state. It is not available when running Power-Up Diagnostics or the Software Loader.

Station Manager Styles

This manual will refer to two different styles of Station Managers. The two styles have a similar interface, but details of the commands and output are different between the two styles.

Station Manager Styles    Style Products Supported

Style A                              IC693CMM321, IC693CPU364, IC697CMM742

Style B                              IC693CPU374

Station Manager Services

The Station Manager provides the following services

  • An interactive set of commands for an operator to interrogate and control the Ethernet Interface.
  • Access to observe and modify internal statistics, an exception log, and advanced user parameters.
  • Password security for commands that change the Ethernet Interface parameters or states.
  • The Station Manager allows you to monitor the operation of the local station (node) and the network. If a problem occurs at the local station or on the network, the Station Manager may be used to pinpoint the source of the problem through the various commands.

Serial Cable (IC693CBL316A) to be used to Connect Personal Computer to Station Manager Port.


Customer Questions and Answers

  • Question: What is an IC693CPU364? Answer: The IC693CPU364 is a single-slot Central Processing Unit (from the GE Fanuc Series 90-30) with an embedded Ethernet cord and 1 built-in serial port.This unit is the "brains" of the PLC and is where most of the calculations take place.
  • Question: What's the first thing you should do when testing your IC693CPU364? Answer: When you attach the IC693CPU364 to a 5 or 10 slot rack and power it up, you should be checking for an OK light.
  • Question: What if I do not have an OK light after I have powered it up? Answer: If you don't have an OK light, then you won't be able to follow through with the test. The lack of an OK light indicates, right from the start, there is something wrong with your IC693CPU364.
  • Question: What is this initial test showing? Answer: You're basically turning on the configuration and logic in this processor in order to set it to run mode. You want to see that this is a good working processor.
  • Question: With what software should I test my IC693CPU364? Answer: You can test your IC693CPU364 with Proficy Machine Edition.
  • Question: What will I need to test my IC693CPU364? Answer: All you will need is your IC693CPU364, a 5 or 10 slot rack, and a power supply.
  • Question: If I think there is a problem with my processor, what should I do? Answer: You should, first, make sure that when you turn on the memory on/off protection switch, the RUN light comes on and then let the processor run overnight (or even 2-3 days). This is to check that it's able to sustain itself in run mode. (You want to make sure it doesn't fail or fall out of run mode for any reason.) If it does fail or fall out of run mode, then you can try reading the faults or errors through the Proficy Machine Edition software. It may give you enough information to help you fix the problem.
  • Question: If I can't figure out how to fix my IC693CPU364, what is my next step? Answer: PDF Supply can repair your IC693CPU364 for you.
