2. Micro-3
3. Micro-3C
4. Click on "Use as Default" to select the most commonly used PLC
5. Selecting CPU/Expansion size by selecting the "Configure" Button
a.) The status line at the bottom of the screen identifies the PLC that WINDLDR is configured to communicate with.

B. Function Area Settings

1. Internal Relay Keep - Selects the point where internal relays will retain their state during a power failure. I.R. below the value selected will retain their on/off status upon loss of power. I.R. above the value selected will be reset to an off status upon loss of power.
2. Input Filter Time Selection
  a.) Catch Input - Designates certain inputs to be able to detect the rapid on/off change of an input to the PLC. This cannot be used for counting repetitive high speed pulse signals such as a proximity switch counting gear teeth. It can be used in a "dragstrip" application where it needs to detect the high speed passing of an object and the next passing will be several milliseconds later after the PLC has completed at least one to two scans.
  b.) Soft Filter - Designates certain inputs to be able to detect input signals faster or slower if contact bounce or faster detection are required to detect.
  c.) Hard Filter - Can be varied from 0 to 255 with a default value of 10. This is used to filter digital input signals from noise which could be detected as a "false on" signal for signals that might only be on less than a millisecond. d.) G1 - Input I 0 selection value in milliseconds for use with the Catch Input and Soft Filter selections to speed up or delay the detection of an input signal.
  d.) G2 - Input I 1 selection value in milliseconds for use with the Catch Input and Soft Filter selections to speed up or delay the detection of an input signal.
  e.) G3 - Inputs I 2 and I 3 selection value in milliseconds for use with the Catch Input and Soft Filter selections to speed up or delay the detection of an input signal.
  f.) G4 - Inputs I 4, I 5, I 6, and I 7 selection value in milliseconds for use with the Catch Input and Soft Filter to speed up or delay the detection of an input signal.
3. 1:N Communication Device No.: - Selects the PLC Node Number when a computer is setup to communicate with multiple Idec PLCs on a network. This establishes the PLC Network Node Number, which is stored within the PLC.
4. Control Data Register Settings - Micro-3 Data Registers D 90 to D 99 can be individually selected to monitor what CPU size is running, PLC and network error codes, Real Time Clock values, and the PLC scan time. Each data register is assigned its own specific task to monitor and they can to monitor these individually.
5. Default - This restores all of the PLC Function Settings to their normal default value.

C. Communication Settings

1. COM Port Selection - Assigns the proper serial port from the computer that the PLC is connected to. This is normally COM 1 or COM 2. If a Serial Mouse (9 Pin D-Sub Connector) is used (normally on COM 1) then try COM
2. If a Bus or PS2 Mouse (small round connector) is used try COM 1.
a.) The Status Line at the bottom of the screen identifies the COM port configured for WINDLDR to use.
2. PLC Network Settings - Determines the PLC Node Number when connecting multiple Idec PLCs to a computer. This makes the networking selection in WINDLDR to determine which PLC in the network to communicate with. Refer also to the PLC Function Settings.

D. Ladder Preferences

1. Display/Hide Rung Comments - Click on "Show Rung Comment" to toggle between displaying or hiding the rung comments.
2. Display/Hide Rung - Click on "Show Rung" to view/print rungs of logic
  a.) This would normally only be hidden to print memonics or boolean when using an Idec Hand Held program Loader
3. Show Tag Name - Normally this is the same as the Allocation Number and appears under the contact/coil
4. Show Allocation Number - This alternates with the Tag name from above and appears below the contact/coil as the Idec PLC Allocation Number Address
5. Display/Hide Mnemonics - Click on "Show Mnemonics" to toggle between displaying or hiding the Hand Held Program Loader programming instructions.
6. Show Machine Code - This appears to the right of memonics and would normally not be viewed/printed
7. Coil Parameters - Typical Settings depending on the monitor:
  a.) Coil Width: 75 b.) Coil Height 22 c.) Line Width: 1
  d.) Tag Comment Lines: 4
1.) Additional Tag Comment Lines can be added but reduces the rungs viewable on the screen 8. Font - Typical setting of Courier New as a Regular font with a size of 10
  a.) This provides a width of 9 characters to be used as the Tag or Label width

COMPILING OF LADDER LOGIC PROGRAM

A. Go to the top menu and select "Compile" and "Convert Ladder"

PROGRAM TRANSFER

A. Go to the top menu and select Online
1. Select "Download" to transfer a program from the computer to the PLC.
  a.) Select Download to PLC or Loader
  b.) PLC Network Type is normally 1:1 which is one computer communicating to one PLC. 1:N is one computer communicating to an Idec network of PLCs
2. Select "Upload" to transfer a program from the PLC to the computer
  a.) The documentation including rung comments and tags will not be displayed when uploading since these values are only stored in WINDLDR not in the PLC.
  b.) When using the Upload command with an existing program name be sure to create a new file name before uploading to avoid deleting the existing rung comments and tags.

D. Timers

1. Format
  a.) All Idec PLC timers are On Delay. b.) Idec PLC timers only require 1 line of control logic.
  c.) Idec PLC timers time down from their preset to 0.
  d.) When power flows through the rung to the timer coil the timer begins timing.
  e.) If power is removed from the timer at any time it will immediately reset itself to the programmed preset value.
2. 1, 10, and 100 millisecond Time Base
  a.) The Micro 1 PLC utilizes timers with a 100 millisecond or a tenth of a second time base. Timing resolution is in 0.1 second increments.
   b.) The Micro-3 PLC utilizes timers with a 1, 10, or 100 millisecond time base. A standard 100 millisecond timer uses a description of TIM. A 10 millisecond timer uses TMH and a 1 millisecond timer uses TMS.
3. Enabling
4. Resetting
5. Cascading 6. Self-resetting

E. Counters

1. Format

a.) A counter requires two lines of logic. The top line resets the counter to 0 (Except on Up/Down Counters). The bottom line of logic pulses the counter

b.) An Up/Down Counter uses three lines of control logic. The top one resets the counter to whatever its preset is programmed at. The middle line of logic provides either an up pulse signal or is the master pulse signal depending on which Up/Down Counter is being used. The bottom line of logic is the down pulse signal or controls whether the counter counts up or down depending on which Up/Down Counter is being used.
