Getting Started
The following procedure outlines the steps required to put your Micro PLC into operation.
Step 1. Unpack the Micro PLC
First, carefully inspect all shipping containers for damage. Unpack the shipping container and verify the contents. Record all serial numbers. For details, see “Unpacking” in Chapter 3.
Step 2. Install the Micro PLC
Mount the Micro PLC on a vertical surface: a wall or panel using screws or on a 35mm DIN rail. The Micro PLC requires a minimum clearance of 1.99 inches (50mm) on each side for cooling.
For details, see “Installation Requirements” and “Installation” in Chapter 3.
Step 3. Connect Ground and Power Wiring
∙For safe operation of your Micro PLC, the installation must meet the requirements of “Grounding Procedures” in Chapter 3.
∙For power connections, refer to the wiring diagram for the Micro PLC model that you have. (See “Field Wiring Installation” in Chapter 4.)
Step 4. Power-up Test
Warning
Ensure that the protective cover is installed over terminals on the terminal board when power is applied to the unit. The cover protects against accidental shock hazard which could cause severe or fatal injury to personnel.
Apply the required power to the system. The Micro PLC should perform a self-diagnostic test. The OK indicator will blink during power-up diagnostics. When self-diagnostics have been successfully completed, the OK indicator will remain lighted. For details, refer to “Powerup Self-test” in Chapter 3.
Step 5. Connect a Programmer to the PLC
Connect a programming device to the RS-422 serial port (Port 1) on the Micro PLC. (Port 2 on 28 and 23-point Micro PLCs does not support configuration and programming.) For cabling diagrams, refer to “Connecting a Programming Device” in Chapter 3.
If Logicmaster 90 software is not installed on your programmer, install it according to the procedures in the Logicmaster™ 90-30/20/Micro Programming Software User’s Manual , GFK-0466.

Frequently Asked Questions
1.What causes a “No Communications” message when I toggle to MONITOR or ONLINE?
Following are a few possible causes:
∙Insufficient conventional memory (at least 545Kbytes) in your personal computer to load the Logicmaster 90 communications driver.
Make sure the config.sys file in your computer is properly configured. For details on configuring your config.sys file, refer to “Software Installation” in the Logicmaster™ 90 Series 90™- 30/20/Micro Programming Software User’s Manual, GFK-0466. For additional assistance, call your personal computer help line or GE Fanuc PLC Technical Support at 1-800-GEFANUC.
∙Configuration mismatch between Logicmaster 90 in your computer and the PLC configuration.
Make sure that the computer and the PLC are using the same baud rate and parity. From the main menu in Logicmaster 90, press F2 to enter the configuration software. To check the computer settings, press F7, Programmer Mode and Setup, and then F4, PLC Communications Serial Port Setup. To check the PLC settings, press F1, I/O Configuration. The PLC baud rate and parity will be displayed in the Software Configuration Screen.
∙Broken cable between your computer and PLC or broken or missing RS-232/RS-422 converter.
For information on installing the converter, refer to Appendix E in this manual.
2.How do you set up the High Speed Counters (HSCs)?
Using the Logicmaster 90 configuration software or a Hand-Held Programmer (HHP), enable each HSC that you want to use. If you want the HSC to drive an output, you must enable its output in the software configuration and set its Enable Output bit in your program or in the data tables. For example, if HSC 1 is configured with its output enabled and its Output Enable bit, %Q505 is set, it will control Q1. (HSC 1 will continually report to the CPU memory location %AI06.) A sample rung that sets the Output Enable bit for HSC 1 is shown below.

For more information, refer to “High Speed Counter/CPU Interface” in Chapter 6 of this manual.
Simple (A-type) counters and A-Quad-B (B-type) HSCs count continuously by default, resetting themselves automatically when a high or low limit is reached. A-type HSCs can also be configured for one-shot counting, in which the HSC counts to one past the limit and then stops.
In one-shot mode, the HSC can be reset by the program using a Communications Request (COMM_REQ) function to write a zero to the Accumulator. The HSC can also be reset by the Preload input. If the counter’s Preload/Strobe parameter is set to PRELOAD (default), the configured preload value will be loaded to the Accumulator when the Preload/Strobe signal goes

Series 90™ Micro PLC User's Manual – June 1998 |
GFK-1065F |

active. For example, if PRELOAD is configured and the default Preload Value of 0 is used, an input on I2 will reset the Accumulator for HSC 1.
For wiring information, refer to the diagrams in “High Speed Counter Inputs” and the wiring diagrams provided in “General Wiring Procedures” in Chapter 4.
Warning
When the Micro PLC goes from RUN to STOP mode, the HSCs will continue to operate. Also, the HSCs will remain in run mode through a power cycle. Therefore, if an HSC is running when power is lost, it will run when power is restored.
3.How do I program the Micro PLC?
You can use a Hand Held Programmer (IC693PRG300) or Logicmaster 90 software (IC640HWP300, includes a 2-meter programming cable) loaded into a DOS-based personal computer. The personal computer must have at least a 386 processor and at least 2 megabytes of RAM.
For a new-user programming lesson, refer to Appendix A of the Software User’s Manual , GFK-0466. Chapter 4 of the Series 90™-30/20/Micro Programmable Controllers Reference Manual, GFK-0467 provides descriptions and examples of programming commands for the Micro PLC.
4. What should I do when I get a “Password disabled” or “insuff icient privilege” message?
There are two possible causes for these messages:
∙Password is set to DISABLE in the Software Configuration screen for the Micro PLC.
The default configuration for password is ENABLE. When changed to DISABLE and stored to the Micro PLC, the setting is permanent. If the configuration is changed back to ENABLE and stored, the “password disabled” error message will be generated and the store will not be allowed. You can either change the configuration back to DISABLE, or use an HHP to erase the program and configuration, thereby restoring the default configuration.
∙Insufficient privilege has been set in the Software Configuration and stored to the PLC.
The OEM password cannot be overwritten. To remove the OEM password, you must use the HHP to clear the PLC memory.
If a password has been set from the level 4 menu and then forgotten, you can override it. This procedure is documented in Chapter 5 in the Software User’s Manual , GFK-0466. (The original program disks are required.)
5.What does it mean when OK LED is blinking or the Run LED is not lighted?
Each time power is applied, the CPU performs a self check for several seconds. The OK LED blinks during the self-test and then changes to a steady on state.
If the Run LED does not light when you go to run mode, the cause could be invalid configuration or a fatal error in the CPU fault table.
