57
Counter Module
This parameter enables a counter to track the number of Heartbeat messages.
Selections:
Disable
no counter field in the Heartbeat message
10
counts cyclically from 0 to 9
100
counts cyclically from 0 to 99
1000
counts cyclically from 0 to 999
10000
counts cyclically from 0 to 9999
Custom
allows defining a custom counter start/stop range from 0 to 10000.
Custom Counter Module
This parameter is available when the Counter Module parameter is Custom. It allows defining the maximum count
number to reach before recycling.
Selections: a number from
2
to
10000
Counter Starting Value
For the Custom Counter Module this parameter selects the starting counter value.
Selections: a number from
0
to
9999
Counter Direction
Sets the counter direction, either
up
or
down
.
System Diagnostics
If checked it enables the System Diagnostics Field in the Heartbeat message. The System Diagnostics field is a fixed 2-
byte field (for the TCNM-AD/EX Family the second byte is always 0). The first byte has the following meaning:
1 = Reading Station OK
3 = Presence Sensor Failure
4 = Reading Station Failure
Network Diagnostics
If checked it enables the Network Diagnostics Field in the Heartbeat message. The Network Diagnostics field is a fixed
32-byte field (one for each scanner in the network from scanner 0 (Master), to scanner 31). Each byte has the
following meaning:
0 = Scanner not expected
1 = Scanner OK
2 = Scanner expected but not present (not connected or possible network failure)
3 = Scanner Failure
Heartbeat Terminator String
This parameter signals the end of the Heartbeat message. It can be a string of up to 128 characters.
Selections: characters from
NUL
(00H) to
~
(7EH)
The Heartbeat Header String should be different from the Heartbeat Terminator String.
Modbus TCP
This option determines the communication between the scanner, or, in a multi-sided layout, between several scanners
and the Fieldbus network.
The Modbus Application Protocol-TCP/IP allows data transmission between the server and client. Both the scanner and
a Quantum family PLC (programmer logical controller) can be either server or client.
This protocol implements Function Code 16(10Hex), which allows copying the application format message into the
registers of the Modicon PLC controller. The application format rules for the Modicon message are the same of the
