PROTOCOL AND OPERATIONAL WORK
This section describes PROFINET protocol, as well as the communication with the
Displays using this protocol.
The notation of the numerical values which is used in this manual is the following:
•
When a
hexadecimal
number is used, the number is followed by “h”
•
When a
decimal
number is used, the number is followed by “d”
•
When a
binary
number is used, the number is followed by “b”
•
When a number is in
ASCII format,
each digit is represented by its ASCII code.
For example: the character X ASCII, can be seen as 58h, 88d or 1011000b. The
number 15 ASCII can be described as 31h 35h, 49d 53d or 110001d 110101d
according to the context.
Definitions of words used in this chapter description;
Message:
Alphanumeric text of one or more lines (depending on the type of display).
The message displayed on each line can be static or dynamic. A static message is one whose
number of characters is less or equal than the number of characters that can be displayed in a
line. The dynamic message will have more characters than characters per line has the display,
and therefore the message will be displayed moving from right to left.
Message code:
Is the number that identifies the message. The range will be: 0 to 512.
Comunication lines:
Is the physical connection between the equipments. There are
two possible communication types: RS-232 (TDL) and Profinet.
The types of communication available in the DT-105/110/203NN displays are:
1. TDL: Developed for this family of display.
2. PROFINET: Network Standard for industrial automation.
Offline:
Operations that must be done on the equipment by means of Display settings
or software tools, previous to the installation or operation of the equipment in the
network.
Online:
Configuration change that can be done with the equipment operating in the
network.
