Chapter 4 System Configuration
Delay between Polls: Here you can configure the delay time between each
Modbus instructions
CRC Check: Here you can enable/disable the CRC check/ignore the CRC error
of Modbus
In the "Rule Setting" tab, you can configure this Modbus address of end devices you
would like to polling.
Rule: There are maximum 8 rules that WISE-4051 support. Each rules can be
different slave devices, in the other word, it can be maximum 8 devices con-
nected to WISE-4051. Or you can use all rules for polling different address of
same slave device.
Slave ID: Different slave devices in same RS-485 has different slave ID, enter
the slave address of Modbus devices which connected to WISE-4051 here
Type: We support 4 kinds of Modbus data type, 01 Coil Status (0x), 02 InputSta-
tus (1x), 03 Holding Registers (4x), and 04 Input Registers (3x). After you con-
figure one of the types in the rule, then this rule will be enabled, and WISE-4051
will start to polling after the configuration been submitted successfully.
Start Address: Enter the first address number that you are going to polling. The
address base is 1, if you are going to polling the first address of Holding Regis-
ters, 40001, please enter number 1 here. Don't need to enter the whole address
40001.
Length: Enter the length of the address that you are going to polling in this rule.
For example, if you are going to polling 40001~40008, enter the length as 8
here. Please be noted that since WISE-4051 can polling maximum 32 address,
the maximum length is 32 addresses, and the total amount of all rules should
also less or equal to 32.
R/W: Here you can decide if the address in this rule will be Read or Written or
not. For Coil Status and Holding Registers, you can make these addresses read
only, or write only to reduce the polling effort.
Scan Interval (in milliseconds): Here decide the scan interval for WISE-4051
to polling Modbus slave devices. WISE-4051 will optimize the scan interval
according you setting. However, the read scan interval may also depend on real
case like: Baud rate, slave devices respond time, delay time between polls, etc.
Go to the Diagnostician page to check the real respond time for referring the
value of scan interval.
Mapping Channel: When the Modbus address of slave devices been config-
ured in each rule, these addresses will also be mapped into WISE-4051. Coils
of Modbus slave devices will be mapped as bits for RESTful web service and
