Product Description


The GE Fanuc IC693CPU351 is a CPU module with a single slot. The maximum power utilized by this module is 5V DC supply and the load required is 890 mA from the power supply. This module performs its function with a processing speed of 25 MHz and the type of processor used is 80386EX. Also, this module must operate within the ambient temperature range of 0°C –60 °C. This module is also provided with a built-in user memory of 240K bytes for entering programs into the module. The actual size available for user memory mainly depends on amounts allocated to %AI, %R and %AQ.

The IC693CPU351 utilizes memory storage such as Flash and RAM for storing the data and is compatible with PCM/CCM. It also supports the features like floating point math for the firmware version 9.0 and the later released versions. It contains more than 2000 timers or counters for measuring elapsed time. The IC693CPU351 is also equipped with a battery backup clock. Also, the scan rate achieved by this module is 0.22 m-sec/1K. The IC693CPU351 contains the global memory of 1280 bits and register memory of 9999 words. Also, the memory provided for analog input and output is fixed which is 9999 words. Memory is also allocated for internal and temporary output coil of 4096 bits and 256 bits. The IC693CPU351 consists of three serial ports which support SNP slave and RTU slave.

System Battery Discharges Before Use

Description

90-30 System Batteries - Discharging at Customer Site

Resolution

Due to a hardware change to prevent the CPU from arriving at the customer ‘DOA’ due to a partially discharged SuperCap, there is a potential for the customer to see another problem in systems with the new SuperCap management circuitry. This problem will manifest itself when the 90-30 power supply and one of the listed CPUs are installed together in a backplane and the system is not powered up within several days. (Note that this is only a problem with the CPU’s listed below.)

What happens in this case is the SuperCap management circuit detects that the SuperCap voltage is below a preset threshold and turns on a switch to hold the voltage rail going to the "battery backed" memories to ground. When a system battery is then introduced, it starts to drain through this switch at a rate of approximately 2mA. A new 90-30 battery can sustain this discharge rate for a maximum of 20 days before it is completely discharged.

To prevent this premature discharge of the battery, two actions can be taken:

  1. Unplug the battery inside the 90-30 power supply until the system is first ready to be powered as described above. Again, the battery will only be drained at the higher rate if the SuperCap is not fully charged.
  2. Do not install one of the listed CPU’s until the system is ready to be powered up for the first time. The application program does not need to be running at this time; this power-up is solely to charge the SuperCap. If the CPU is powered up for approximately 10-15 minutes, the SuperCap will be charged and the system battery can maintain this SuperCap charge and supply memory retention power to the CPU for the normal expected in-service life of the battery after the power is removed.

Using LREAL in ME View To Access PLC

Description

When using an LREAL variable with a PLC Access Driver, it will take the 32 bits starting from the address set in the reference for the variable.

Resolution

For instance, using a Modbus PLC Access Driver set to communicate with address 80001 in a Series 90-30 PLC with an IC693CPU351 configured for an RTU slave, it will access modbus address 40001 (%R00001) and read 32 bits. This can be viewed in the PLC reference tables by changing the format of %R00001 to DWord.

 

Customer Questions and Answers


  • Question:  What is an IC693CPU351?  Answer:  The IC693CPU351 is a single-slot Central Processing Unit (from the GE Fanuc Series 90-30) with 2 built-in serial ports. 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 IC693CPU351?  Answer:  When you attach the IC693CPU351 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 IC693CPU351.
  • 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 IC693CPU351?  Answer:  You can test your IC693CPU351 with Proficy Machine Edition. 
  • Question:  What will I need to test my IC693CPU351?  Answer:  All you will need is your IC693CPU351, 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 IC693CPU351, what is my next step?  Answer:  PDF Supply can repair your IC693CPU351 for you. 
  • Question:  Things you should also be testing:  Answer:  You should make sure that both ports are working by plugging into them and making sure the LED lights come on when you do plug into them.
