Standard Mode
The following table illustrates the memory use for 500 messages and a
maximum number of data sets containing 22 bytes of user data:
You can use the following formula to determine the exact message
buffer size:
G >= M1 + M3 + 20
G = Size of message buffer
B = Size of parallel message system in bytes
M1 = Number of messages which: require only 1 memory location, are
entered in the message editor and have message numbers smaller
than B x 8
M3 = Number of messages which: require 3 memory locations, are
entered in the message editor and have message numbers smaller
than B x 8
20 = Minimum size of message buffer
5.25 Application ID
You can use the application ID to identify any application.
The application ID is stored in the project’s S3 file and is therefore
stored in the operating device after the download. The same ID is
stored in the project management file.
You can compare the IDs of a project management file with that of an
S3 file.
You can also compare the IDs of an S3 file and operating device con-
tent. To do this, you must establish a connection between the PC and
the operating device (download cable).
