The PT46xDN Transmitter supports Polled I/O Messaging to read “real-time” data. It does not support
Cyclic I/O, Change of State (COS), or Bit-Strobe connections. The control system Master must be configured
first 8-bit word (Byte 0) of the I/O Message Response as shown in Table 1. Note that the most significant
4 bits of the first byte are reserved for future use. The next 8-bit word (Byte 1) supplies transmitter status
information, e.g. reading valid, electronics fault, etc. Further information on alarm and status bits is
available in Section 7.4. The remaining 2 8-bit words (Bytes 2 & 3) represent the Pressure Value (PV).
