GE VersaMax IC200PWR001 User Manual page 449

Mixed Module, 24 V DC Positive Logic Input 20 Points / Output 12 Point /
(4) High-speed Counter, PWM, or Pulse Train Configurable Points
Configurable Features
The module can be software-configured when it is installed in a VersaMax PLC
system, or an I/O Station controlled by a Network Interface Unit that is version
2.0 or above.
Parameter Description
Counter Type If 1 Type B & 2 Type A is selected, counter #1 parameters
are used for the Type B counter (except Counter #1 Direction
and Counter #1 Count Input Edge parameters) and counter #4
parameters are used for the Type A counter.
Defines what outputs do if the system is in stop mode. Normal
Output Stop Mode
means that HSC outputs continue to respond to the counter
inputs and standard outputs turn off. Preset outputs, continue
to operate as if the CPU/NIU were present, changing state to
reflect the counter Accumulators.
Force Off means all Preset outputs are turned off and remain
off until the CPU/NIU returns to normal operation.
Hold Last means Preset outputs retain current levels and do
not reflect the counter Accumulators.
Channel #1/2/3/4 Specifies channel function.
Function
Counter Output Specifies if the counter output is enabled. If disabled, the
#1/2/3/4 Enable output is used as a standard output.
Counter #1/2/3/4 (Type A only). Specifies whether count inputs increment or
Direction decrement the accumulator.
Counter #1/2/3/4 Defines whether the counter wraps if the count limit is reached
Mode (continuous) or if it stops at the counter limit.
Counter #1/2/3/4 Specifies the function of the Preload/Strobe Input.
Preload/Strobe
Selection
Counter #1/2/3/4 For Type A counters only, specifies which transition of this
Count Input Edge for input is used. Positive is a low-to-high transition.
Type A
Time Base #1/2/3/4 Specifies the timebase for the Counts-per-Timebase register.
High Limit #1/2/3/4 Defines the counter's upper limit. It must be greater than the
low limit
Low Limit #1/2/3/4 Defines the counter's lower limit.
ON Preset #1/2/3/4 Defines the counter's ON preset. When the count is at or
above this value, the HSC output is turned on.
OFF Preset #1/2/3/4 Defines the counter's OFF preset. When the count is at or
above this value, the HSC output is turned off.
Preload Register This register value is the Preload value for the counter.
#1/2/3/4
Home Value The Home Value for the counter.
Acceleration Pulse Train acceleration rate from stop to full speed.
Deceleration Pulse Train deceleration rate from full speed to stop.
