GetCount - method of the PmaCommGroup object

Description:
The method returns the number of transfers of this object.
Syntax:
Long GetCount(Long nType)
Parameters:
nType(Long) Specifies transmissions in this object whose number we want to get.
 
Number of transfers since data receive and data send:
0 - The number of all transfers (successul and failed) since application launch (= GetCount(1) + GetCount(2))
1 - The number of all successful transfers since application launch (= GetCount(11) + GetCount(21)).
2 - The number of all failed transfers since application launch (= GetCount(12) + GetCount(22)).
3 - The number of latest failed transfers. This number is set to 0 after every successful transmission. (= GetCount(13) + GetCount(23)).
 
Number of transfers since data receive:
10 - similarly to 0 (= GetCount(11) + GetCount(12))
11 - similarly to 1
12 - similarly to 2
13 - similarly to 3
 
Number of transfers since data send:
20 - similarly to 0 (= GetCount(21) + GetCount(22))
21 - similarly to 1
22 - similarly to 2
23 - similarly to 3
Note:
By the term "transmission" is here understood the action that is finally terminated by the onDataReceive event. If the "Number of repeats after unsuccessful transmission" configurator is greater than 1 in the serial link parameters (or in the Ethernet parameters), then the message is repeated more times on error but from the point of this statistics it is only 1 transmission.

Example:
If communication error occurs 5 times in a row in this object, then notify (e.g. call the alarm, etc.)
