channel.getcount()

Remarks,

continued

If an error is detected, a nil value is returned. No partial list of close counts is

returned.

When the channel list parameter for this function is 'slotX', the response first lists

the channels starting from lowest to highest. After the channels, backplane relays are

listed starting with lowest bank first and increasing to the highest.

When the channel list parameter for this function is 'allslots', the response

starts with Slot 1 and increases to Slot 6. Each slot is processed completely before

going to the next. Therefore, all Slot 1 channels and backplane relays are listed before

Slot 2 channels.

For digital I/O, DAC, and totalizer channels, zero is always returned.

Query commands (on page 13-6)

Example

To see the close counts for Channels 1 to 5 on Slot 2:

counts = channel.getcount('2001:2005')

To see the close counts for all channels and analog backplane relays on Slot 3:

counts = channel.getcount('slot3')

To see the close counts for channels and analog backplane relays in channel pattern

called 'mypath':

MyPathList = channel.pattern.getimage('mypath')

print(MyPathList)

print(channel.getcount(MyPathList))

print(channel.getcount('mypath'))

channel.getdelay()

Function

Queries for the additional delay time for the specified items.

Usage

stime = channel.getdelay(<ch_list>)

ch_list: A string listing the channels to query for their delay time.

stime: Returns a comma-delimited string consisting of the delay times (in seconds) for

items specified in ch_list.
