Status Information
6.0 Status Information
6.1 Device Status
The converter sets a device status variable to indicate certain conditions.
Bit Device Status
0 The PV is beyond its operating limits
2 The loop current has reached its upper (or lower) endpoint limit and cannot increase (or decrease) any further
3 The loop current is being held at a xed value and is not responding to process variations
4 "More Status Available" whenever any failure is detected. Command #48 gives further detail. (See Section 7.3.)
5 A power failure or device reset has occurred.
6 An operation was performed that changed the device’s conguration.
7 The device detected a serious error or failure that compromises device operation.
6.2 Extended Device Status
This Field Device does not use the “Extended Device Status”.
6.3 Additional Device Status (Command #48)
Command #48 returns 1 bytes of data, with the following status information:
Bit Meaning Class
Device
Status
Bits Set
0 Flow Rate Overow Error 4 - 7
1 Pulse overow 2 Error 4 - 7
2 Pulse overow 1 Error 4 - 7
3 ADC Signal Saturation Error 4 - 7
4 Excitation Error Error 4 - 7
5 Cumulative Inputs Errors Error 4 - 7
6 Input Amplier Signal Saturation Error 4 - 7
7 Pipe Empty Error 4 - 7
"Not used" bits are always set to 0. All bits used in this transmitter indicate device or sensor failure, and therefore also sets
bit 4 of the Device Status byte (Additional Device Status) and bit 7 (Device Malfunction). These bits are set or cleared by the
self-test executed at power up.
7.0 Universal Commands
The Field Device implements all Universal Commands. Some details below:
Command Details
3 It returns PV, SV, TV and QV. See Section 6.
14 It also returns the sensor S/N
