TIP

Master/Slave State

The serial port scan block can be configured in the master state to acquire data from the slave serial communication equipment connected in a certain time interval. In the slave state, the DataSite controller can receive commands from the host, generate and return response message. For more information, see the

Configuration Example

Timeout

In the master state, timeout is the maximum length of waiting time after a command is sent. No new commands are sent while waiting for a response. If no response is received after timeout, an error message box will be displayed to inform you. You will then be prompted to send a new command.

on page 50.

Verify the protocol setting. If you set the protocol as "None", the scan and the trigger scan function blocks will not run properly even if the Master/Slave state is set correctly.

Timeout is not applicable in other states.

Delay Time

In the master state, delay time is the maximum length of waiting time for the next send command after one send/receive cycle is completed. This setting can help prevent communication errors caused by a slower response of the slave communication equipment connected.

In the slave state, delay time is the maximum length of waiting time for a response to be returned after a command is received. This setting can help prevent communication errors caused by a slower response of the master communication equipment.

TIP

Settings

For integrated modules such as the DataSite controller, the master ports can directly read/write parameters by accessing the fixed Modbus registers. We need to set scan blocks of US1 and US2 only when we want to access other pieces of equipment connected with the two serial ports (COM1, COM2).

Use Scan Settings to match the register addresses of the 1758 controller with those of the serially connected equipment.

A custom function block that can be triggered in the user program to provide Modbus Master read/write functions is also available. For more information, see the DataSite Customized Function Blocks Reference Manual,

1758-RM001

When the address of the master or slave register does not map to the signal, the following error will appear.

Scan Time

Scan time refers to the read-write time interval of a scan block. You can use the trigger scan function for COM port by programming the function block COM_MSG in DataSite Workbench.

The following units of time are available. Note that ms represents milliseconds, s seconds, m minutes, and h hours:

• 50 ms

• 500 ms

• 5 s

• 50 s

• 5 m

• 50 m

• 5 h

• 50 h

Publication 1758-UM002D-EN-P - October 2010

38 DataSite Configuration Settings Utility (DS Settings)

The scan time is equal to the value multiplied by the unit selected. For example, if the value entered is "3" and the unit selected is "500 ms", then the scan time is 3 x 500 ms = 1500 ms as shown in the following dialog box. This means that the current scan block will be executed every 1500 ms.

Scanning starts when the DataSite controller is powered, and it continues according to the scan time you have set.

Master Register

This is the start address of the register on the DataSite controller. Data is saved into the master register starting from this address. The address range is determined by the signal type.

Slave Register

This is the start address of the register on the slave equipment for reading data from and writing data to. The controller will read data from or write data to the slave equipment from this address. The address range is determined by the signal type.

Reg_Num

The number of read/write data registers that follow the start register address of the master register and the slave register. For example, if Reg_Num is 10, the Master Start_Register is 40001 and the Slave Start_Register is 41001, this means there are 10 master registers with register addresses running sequentially from 40001…40010, and 10 slave registers with register addresses 41001…41010.

Remark

This field lets you enter a note or a tip for the scan block. This information can be saved onto the PC but unlike other parameters, it will not be downloaded to the DataSite controller. The maximum string length for this field is 90 characters.

DataSite Configuration Settings Utility (DS Settings) 39

Err_Cnt and Err_State

These two parameters do not require user configuration. If you set up a scan block successfully, two columns for these parameters will be added in the scan block list automatically.

The Err_Cnt value represents the number of times the scan block fails to communicate with the slave device. After the scan block is configured, if there is no connection with the slave device or if communication fails, this value will be incremented by 1 after each scan cycle.

This value is an indication of the status and efficiency of the communication. For example, if the value keeps incrementing, this means that the communication has failed. This could be due to a faulty physical connection between the DataSite controller and the slave device, or due to incorrect parameter settings. In addition, a low value indicates a more efficient communication.

If the Err_State value is 1, it means the communication has failed. A value of 0 indicates that the communication is OK.

Configuration Example

By configuring a scan block as a US1 or US2 block, we can read from and write to the equipment connected with the DataSite controller.

For example, we can take two DataSite controllers connected via RS232 serial communication, with COM1 of one DataSite controller as the master station, and COM1 of the other controller as the slave station. The master station can read/write the slave station’s signal via the serial communication between the two stations.

The following subsections provide you with one way of configuring the DataSite controllers in this example.

Here is an example of a HART configuration list:

Understand HART Commands

Some of the variables read from HART equipment are 32-bit floating-point values. Every floating-point value is stored in two continuous data registers. The higher 16 bits of this value will be stored in the register with a higher address and the lower 16 bits of this value will be stored in the register with a lower address. For example, if a 32-bit double precision IEEE floating point number, such as 1234.5678 is to be stored, two registers, such as register 40108 and register 40109 can be combined to store the number. In hexadecimal,

1234.5678 is 449A 552B. The DataSite controller will store 449A in register 40109 and 522B in register 40108.

Variable and Command

Each piece of HART equipment is designed differently. For example, when you use command 3 to read variables from HART equipment, the four dynamic variables returned may have different meanings, and not all four variables may be valid. Refer to the documentation for the HART equipment for more information. See also the table, Description of HART commands

Response Message

The response message of a piece of HART equipment contains the Err Num and Err State values. The Err Num value indicates the number of times communication with the HART equipment has failed. The Err State value indicates whether communication with the HART equipment is a success or failure. An Err State value of 0 means that communication with HART equipment is successful. An Err State value of 1 means that the communication with HART equipment has failed.

You can also read the response code from the HART equipment. It is stored as two bytes in the state register which you have configured in the HART scan block. If bit 7 in the first byte is 1, this byte is bit-mapped and all the communication errors are displayed in this byte. If bit 7 in the first byte is 0, this byte is not bit-mapped and the meaning is determined by the value of bit 6 through bit 0.
