There may be some few cases where memory availability is severe enough to require adjusting the values to enhance the performance of the overall project. The Main Driver Sheet will optimize the user entries according to the limitations mentioned above number of devices, data types, request size to create the lowest number of Virtual Read Groups that will be required to scan all configured tags. This receive buffer memory is also allocated and de-allocated as required. If the Communications Settings dialog in IWS for a particular driver, such as MOTCP, allows the user to enter a block size, the value entered is limited to the maximum block size allowed by the logical protocol. For more information, see Use the Object Finder to select integrated tags.

The Main Driver Sheet will optimize the user entries according to the limitations mentioned above number of devices, data types, request size to create the lowest number of Virtual Read Groups that will be required to scan all configured tags.

Additionally, the TWCAT driver uses controller tag names exclusively, and the OMRON and ABCIP drivers can be configured to use either block addressing or controller tag indusofft in their later releases, so the rules for block size and address ranges covered below will not be the same in those modes.

It then de-allocates this transmit buffer memory so it is available to other tasks. There may be some few cases where memory availability is severe enough to require adjusting the values to enhance the performance of the overall project.

Only one main driver worksheet may be used, and it triggers every milliseconds, though this can be changed if desired. The range defined by the highest and lowest addresses configured in the Standard driver worksheet must conform to what is allowed in a abcp request for the specified data type. These operations are fairly independent.

When configuring the Standard driver worksheet for a given protocol, you will need to use something of a trial and error methodology to establish that limit for each of the data types you configure. The Communications Settings dialog provides a field for configuring the size of both the Transmit Buffer and the Receive Buffer in some cases.

When you configure a Standard driver worksheet, you will notice that there is only one Station field for the entire worksheet.

Remember, each time a Read Trigger occurs, the request for this worksheet is added to the queue if there is not one already there. The standard driver worksheet has a flexible triggering configuration, and users are allowed different standard driver worksheets. Click OK to finish the configuration and add the source.

By default, port is assumed. Main Driver Worksheet The main driver worksheet is not available for all drivers, but the majority of drivers support it. This driver worksheet is optimal for an easy configuration, but may have less flexibility. You should also be aware that the Write Trigger field on a Standard Driver Sheet has its own behavior.

The triggering is more flexible on these worksheets, however, and should be understood well in order to optimize the driver task for your needs if the Main Driver Sheet does not suffice.

The Memory Area dialog box is displayed. Memory Area dialog box. In the Name box, type an appropriate name for this tag integration source. Note that the name will be used as a prefix on names of the integrated tags. Typically, there are always requests in the queue to be sent each time the driver task is granted its time slice, When a value changes on the Indusoft side for a tag that is configured in the MDS, a Write Item request to the associated device is immediately placed on the top of the queue for that specific tag, and has priority over any other requests already in the queue.

Again, putting the tag BlinkFast in that field is not going to guarantee a request for this worksheet will be sent every ms. Each type of driver worksheet has its own unique advantages.

In these cases, the buffer size will not apply at all, and any block size limitation would be imposed by the API itself. You can view these virtual groups by right clicking on the driver icon on the taskbar during runtime and selecting Virtual Read Groups from the popup menu. This receive buffer memory indusodt also allocated and de-allocated as required.

In the Size box, type the size in bits of the memory area. You can configure a tag to be toggled at a specific rate using the Indusodt, and place that tag in the Read Indusoftt field. Communication tab of the Project Settings dialog. There are additional fields in the header portions of both types of driver worksheets not covered here, and they are useful in your overall scheme, but the basics presented here should be useful in providing up-front knowledge that can help with your PLC configuration scheme, your Indusoft Communications configuration scheme and may perhaps affect the way you configure other tasks in the Indusoft Web Studio project.

Block Size If the Communications Settings dialog in IWS for a particular driver, such as MOTCP, allows the user to enter a block size, the value entered is limited to the maximum block size allowed by the logical protocol.

The Standard Driver Sheet will generate a request for the range of register values defined by the highest and lowest addresses specified in the body of the worksheet. The driver task consists of two main operations, building the queue stack of requests and executing the queue. In the Type list, click Integrated.
