10.2.2 Input Status
Input Status allows the Modbus mapping of a device with single or multiple binary output. As
Fieldgate SWG70 supports extended registers, values are normally assigned to the registers with the
reference addresses 100001 to 165536. The reference addresses are obtained by adding the register
number to 100,000. The dialogue checks for completeness of entries (line turns red if not correctly
filled out) as well as double assignment to the registers (line turns yellow).
The algorithm assumes that the discrete device delivers a maximum of 256 packed discrete values,
each of comprising 16 bits of an unsigned Integer16 (UINT16). Each bit represents a unique input
status. Fieldgate SWG70 first splits the data into two bytes and reserves 8 registers for each byte,
i.e. one for each bit contained.
• Least significant byte (Bits 0 - 7) maps e.g. to registers 100001 - 100008
• Most significant byte (Bits 8 - 15) maps e.g. to registers 100009 - 100016
The value entered after the byte selection determines which of the packed discrete values is to be
mapped, e.g. 0 will map the first set of packed discrete values and 15 the sixteenth set of packed
discrete values. More information is to be found in Appendix A.2.2.
NOTE!
• Some HART devices map their discrete value and status as PV in HART CMD 3. In this case the
value and status information will be found in the appropriate Input or Holding Register,
see Chapter 10.2.3.
• If a device status is mapped as a UINT8 to the Input Status registers, the status will be found in
only one of the bit registers, e.g. in Bit 0. The UINT8 is stored as a 16-bit value, the MSB being
filled with "0"s, see Chapter A.1.3.
