Modbus Configuration - Rule Setting Tab
In this tab, you can configure the Modbus address of end devices you would like to
poll.
Rule: There is a maximum of 30 rules that each COM port can support. Each
rule can be for a different slave device, meaning that there can be a maximum
30 of devices connected to the COM port. Alternatively, you can use all of the
rules for polling different addresses on the same slave device.
Slave ID: Different slave devices in the same RS-485 port have different slave
IDs; enter the slave address of the Modbus devices that are connected to the
WISE module here.
Type: This device supports Modbus data types: 01 Coil Status (0x), 02 Input
Status (1x), 03 Holding Registers (4x), and 04 Input Registers (3x). After one of
the types has been configured in the rule, the rule will be enabled and the COM
port will start polling after the configuration has been submitted successfully.
Start Address: Enter the first address number that you are going to poll. The
address base is 1; if you are going to polling the first address of a holding regis-
ter (i.e., 40001), then simply enter the number "1" here (you do not need to enter
the entire address "40001").
Length: Enter the length of the address that you are going to poll in this rule.
For example, if you are going to poll 40001~40008, set the length to "8." Note
that since each COM port can poll a maximum of 64 addresses, the maximum
length is 64 and the total number of all rules should not exceed 64.
R/W: Here, you can set whether the address in this rule will be read or written.
For coil statuses and holding registers, you can make these addresses read-
only or write-only to reduce the polling effort.
Scan Interval (unit: s): Here, you can set the scan interval for the COM port to
poll Modbus slave devices. The COM port will optimize the scan interval accord-
ing your setting. However, the read scan interval may also depend on factors
such as the Baud rate, slave device response time, delay between polls, and so
