postCard

The postCard element contains block elements that define the terminal communication parameters for all cards in a Modbus DynaCard request. Block numbers must be unique across all preCard, card, and postCard sections. The block numbers in the postCard section must be greater than any block number in the card section. Use of the postCard section is optional, and varies by field device.

This element is:

• Case sensitive
• Not required in a DynaCard-enabled, Modbus device template file
• If used, used 1 time per cardBlocks element

To learn about how this element relates to other elements in a CygNet device template file, see Device Template File Hierarchy.

Attributes

The following table lists and describes attributes generally applicable to this element. However, not all of the attributes listed here are applicable to all EIEs. Additionally, some attributes are required for use in every device template file of a certain EIE, but others may be used on a case-by-case or device-by-device basis, depending on your specific needs. All attributes in templates are case sensitive; but the case sensitivity of attribute values is based on context.
