Sets or queries whether the bits in the status byte are detected
IM
or masked
Command = IMm<CRLF> -> Answer = IMm<CRLF>
Command = IM?<CRLF> -> Return = IMm<CRLF>
Sets whether each of the bits in the status byte is detected or
masked. (Querying is performed using the ESC S command.
See section 6.6.)
If you specify IM0, all the bits are masked. If you specify IM63,
all the data bits reflect the current status.
Parameter
m = 0 to 63
1: bit0 (measurement completion) is detected
2: bit1 (output adjustment completion) is detected
4: bit2 (syntax error) is detected
8: bit3 (overrange) is detected
16: bit4 (24 V loop output error) is detected
32: bit5 (output error) is detected
(Bits 6 and 7 of the status byte are fixed bits.)
The default is m = 63 (no masking)
Sets or queries whether the internal resistor for HART
IO
communication is on or off
Command = IOm<CRLF> -> Answer = IOm<CRLF>
Command = IO?<CRLF> -> Return = IOm<CRLF>
Parameters
m = 0: 250 Ω resistor off (default)
If the CA450 is in any mode other than loop power
measurement mode, ERR13 is returned.
1: 250 Ω resistor on
