In this example the driver reads the hold time from the field device. The time is stored in 3 consecutive Data Array elements. To read Sample Times simply change the Met1_Function to ‘Sample Time. The driver extracts the time from the response and stores rd the hours at the specified offset, the minutes in the next Data Array location and

In this example the driver writes the hold time to the field device. The time is specified in seconds. A max of 23 hours 59 minutes and 59 seconds can be specified. To write Sample Times simply change the Met1_Function to ‘Sample Time. The driver extracts the time from the response and stores the hours at the specified offset, the minutes

In this example the driver sends a command to start or stop the field device from counting based on the value found in the Data Array element. If the value is non-zero, the field device will be commanded to start counting. If the value is zero, the field device will be commanded to stop counting. In this example the function is set to wrbx which means the com

The command sent is determined by the value found in the specified Data Array location. In this example the function is set to wrbx. This means the command message will be sent each time the value found at the specified offset in the specified Data Array is updated even if it is not changed

Map Descriptor Example 6 – Select Device Device selection is handled automatically by the driver, and support for this message is provided mainly for testing purposes. The driver uses the Node_ID parameter to learn the address/number of the device to be selected. Valid numbers are in the range 1...64. When the device responds the driver stores the device number the Data Array element specified in the confi

Map Descriptor Example 7 – Read the Current Record In this example the driver reads the current record and stores the values in the specified Data Array. A single record comprises the following data: status; date and time and a count for 1 or more locations. The driver has no advance knowledge of the number of count fields to expect in the response. It simply stores them in consecutive locations in the Data

The one difference is that a secondary Data Array has been specified. When this is done, each time a response is received, in addition to the storage specified in the previous example, the driver dumps the response byte for byte the secondary Array. It is important to avoid overlaps in the secondary a

This example is similar to the one in example 7 where the current record was read. Here passive Map Descriptors have been added to store specifically labeled count records in specific places. In addition to the normal storage of the response data, the driver examines the label which precedes each count value and looks for a matching M
