i.

In the “Baudrate(COM2)” field, select the WISE-580x COM2 data transmission Baudrate from the drop down list. The Baudrate has to be set the same as the Baudrate of Modbus RTU Slave modules. Please note: on the I-7000 Module Setting page, there is a COM2 Baudrate setting as well, please note that all I-7000 modules and Modbus RTU Slave modules that are connected to the WISE-580x COM2 must be set to the same Baudrate.

ii.

Select the data transmission Baudrate for WISE-580x COM2, and then the system will automatically provide a proper value in the “Silent Interval” field. For each Modbus RTU Slave device has different Modbus command process capability, the response time for sending result from Modbus RTU Slave device to controller might be different. You can adjust this value to most appropriate time interval, such as: extend this value to make sure every Modbus RTU Slave device connected to the WISE-580x has enough time to process the Modbus command, or shorten this value to improve the efficient of the poll mechanism between Modbus RTU Slave device and WISE-580x.

iii.

In the “Mode” field, select the I/O module connection mode for this WISE-580x. There are two options; if you select “4 Modbus RTU Modules + 16 I-7000 Modules”, the address of the Modbus RTU Slave module has to be set between 17~20. If the option “10 Modbus RTU Modules” is selected, this WISE-580x is set to connect to Modbus RTU Slave modules only and the address of the Modbus RTU Slave module in this mode has to be set between 1~32.

iv.

In the “Address” field, select the correct address for the Modbus RTU Slave module. Please note: the configuration of the address must be the same as the Modbus RTU Slave module address setting.

v.

In the “Name” field, input the Modbus RTU Slave module name. This name will be used in IF-THEN-ELSE rule edition.

vi

Input the “Polling Timeout” field. The “Polling Timeout” indicates the time interval for WISE-580x to send command to the Modbus RTU Slave module and wait for the response, the unit is millisecond.

vii.

Input the “Timeout Retry Interval” field. The “Timeout Retry Interval” indicates the time interval for WISE-580x to resend command to Modbus RTU Slave module when it’s in the timeout status when performing communication between WISE-580x and Modbus RTU Slave module. The unit is second.

viii.

After finish the settings of ”Baudrate(COM2)”, “Silent Interval”, ”Mode”, ”Address”, “Name”, “Polling Timeout” and ”Timeout Retry Interval”, click “Add” button. The new Modbus RTU Slave module will be added to the module list. The order of the Modbus RTU Slave module will vary according to the mode selected. If you select the mode that supports 4 Modbus RTU modules, the Modbus RTU Slave modules will be added in the order of the address 17~20. If you select the mode that supports 10 Modbus RTU modules, the order of the Modbus RTU Slave module will correspond to the Index number the Modbus RTU module being assigned (not correspond to the RS-485 address). So before you add the module, you must assign a specific Index (1-10) to a specific Modbus RTU module. According to the Index being assigned, the I/O channel data of the module will be saved in the corresponding WISE-580x Modbus address table, for more detailed information, please refer to Appendix 1 in user manual.

The following are examples of the Modbus RTU Slave module lists.

▲Modbus RTU Slave Module List for “10 Modbus RTU Modules”

ix.

Click on the Modbus RTU Slave module on the module list and click “Setting” button to get in to the Coil Output, Discrete Input, Input Register and Holding Register setting page to edit settings. To remove the Modbus RTU Slave module, select the module you would like to remove and click “Remove” button. To relocate Modbus RTU Slave to other address, click “Move Up” or “Move Down” to move the Modbus RTU Slave module to the desired address(for “4 Modbus RTU Modules + 16 I-7000 Modules” mode) or the desired Index(for “10 Modbus RTU Modules” mode).

x.

After all Modbus RTU Slave module settings are completed, click “Save” button to save the changes.

If the Modbus RTU Slave device provides HEX data only, WISE-580x allows to transfer the HEX value to decimal value in floating point so that the value can be used in IF-THEN-ELSE rules edition. The value retrieved from WISE-580x via Modbus TCP/RTU can be transferred to more-easy-to-read decimal value in floating point automatically as well (the floating point will take two local addresses).

When you select HEX as the data type, you will be required to input the HEX data range and the corresponding decimal data range. WISE-580x will transfer the HEX to decimal value automatically when performing read/write operations.

Identify the status of Coil Output to be ON or OFF, if the result matches the evaluation criteria, the Action will be executed.

Identify the status of Discrete Input to be ON or OFF, if the result matches the evaluation criteria, the Action will be executed.

Identify the value of Input Register to be equal to, greater than, less than, equal to or greater than, equal to or less than the "Variable", if the result matches the evaluation criteria, the Action will be executed.

Identify the value of Holding Register to be equal to, greater than, less than, equal to or greater than, equal to or less than the "Variable", if the result matches the evaluation criteria, the Action will be executed.

Change the Coil Output status to specified status. The status can be set as "OFF" or "ON".

Users can modify the Holding Register value in the THEN/ELSE Action statement.

Holding Register	Operator	Variable	Description	Execution Type
Holding Register Value of Address N	= += -=	Self-Defined Value	The value defined by user.	One Time / Repeat
	Operator Description
	=	Assign the new Holding Register value as the value in "Varibale" field.
	+=	Assign the new Holding Register value as the original Holding Register value plus the value in "Varibale" field.
	-=	Assign the new Holding Register value as the original Holding Register value minus the value in "Varibale" field.
