Pic 64 Limits verification
To create and/or edit list of limit’s values use file limits.csv, that is in program’s folder. This file
can be edited by MS Excel.
Event code it is not analyzed and can be used few times per system, so you can
set setting for few limits. But form other side, if you will use the same code for a
few register, this can mislead you by sending alerts on diggerent events, so use it
carefully.
7.14 Alerts
7.14.1 Alert over Ethernet settings [Alerts>Configuration].
Select check box to Enable alert over Ethernet function. Enter destination Modbus TCP/IP
servers IP address and Port, change time values if you need and set data.
If you did everything correct, on every deviation, the alert message will be sent.
Information transfer algorithm:
1. Data logger makes connection to server, over Ethernet TCP socket.
2. By Modbus TCP/IP protocol, using function nr. 16, deviation report will be sent to server
(in register list, information is stored in registers, starting from address nr. 64000). Sent
report contains:
•
Unique data logger number;
•
Data logger IP address;
•
Deviation identifier (see chapter 8.7)
3. When answer into function nr. 16 is received, data logger disconnects from TCP socket.
4. When server get’s deviation information, it initializes connection with data logger and
over Modbus TCP/IP read all details about deviation
5. If connection with server was not established over the set (connection to server time)
number of tries, data logger will try to connect after some time.
If opening of socket is succeeded, but server do not answer into Modbus function 16, data logger
