Counting the Ways to Use the ESC Counter Channels

With the 8864, ESC introduced Type N – Counter channels. This is an exciting feature that expands the functionality of the 8864 data controller. While some of this functionality can be accomplished using an 8832 data controller, there are multiple benefits to using the Type N channel in an 8864 data controller. Those benefits are as follows:

  • Provides a greater range of functionality. Some of the more complicated counting and averaging functions simply cannot be configured in an 8832 data controller.
  • Configuring this functionality is easier. Configuring a type N channel is much more straightforward than the multiple pieces of logic needed to perform this function in an 8832 data controller.
  • Keeps the configuration clean. There is no need for excess parameters or digital events to perform this single function. M-type math channels take the instantaneous values of the constituents of an equation and evaluates them, then averages the values together to get the desired interval value.

Counter channels are only available in 8864 data controllers with firmware v5.00 or later. On a basic level, this channel is a counter. However, much can be done by using just a simple counting mechanism. Counter channels are typically used to perform one of the following tasks:

  • Count the number of times an event occurs. For example, you may want to count the number of startup events that take place.
  • Track duration of an event. For instance, how much time is spent in startup during each startup event.
  • Accumulate values during an event. Such as, the total emissions during startup events.

M-type math channels take the instantaneous values of the constituents of an equation and evaluates them, then averages the values together to get the desired interval value. In a P-type math channel, the interval values of the constituents are used to produce the channel value for that interval.
