6.8.3. Increasing the Amount of Periodic Input Data
E.g. “TeSys U no. 2” motor starter. We are trying to complete the monitoring of this motor starter starting from the currently monitored register, that is to say “TeSys U Status Register” (address 455 = 16#01C7), and going as far as the “Reserved: 2nd Warning Register” (address 462 = 16#01CE). The number of registers monitored is therefore increased from 1 to 8.
In this case, there are quite a lot of operations to be carried out. They are described in order below:
1)Changing the number of registers monitored: This step consists of changing the value of “Number of points (Hi, Lo)” element of the “Query” from the “Read Holding Registers” command (Modbus command for reading the values of a number of registers). Select this element, then change its value as shown below. AbcConf will automatically convert any value entered in decimal to hexadecimal.
2)Changing the number of data bytes in the Modbus response: The number of bytes read from the “TeSys U n°2” motor starter memory increases from 2 to 16, as the number of registers monitored has increased from 1 to 8. Select the “Byte count” element from the “Response” and change its value as shown below. AbcConf will automatically convert any value entered in decimal to hexadecimal.
