Emerson Rosemount 2410 - Digital Input; Pressure Value

5.11 Digital input
The K1 and K2 relay input status can be included in the Sakura V1 protocol response. The
digital input value is customized as shown in Table 5-9.

Value Decoded
ASCII char
Description
30h 0 K1 and K2 energized (or function disabled by holding register
MiscCtrl bit 6, see Table 5-6)
31h 1 K1 de-energized and K2 energized
32h 2 K1 energized and K2 de-energized
33h 3 K1 and K2 de-energized
Note
This function must be enabled by the MiscCtrl register status bit 6. See Table 5-6.
5.12 Pressure value
There are three pressure values in the Sakura V1 protocol: P1, P2, and P3. They are by
default configured as:
• P1: Liquid pressure
• P2: Middle pressure
• P3: Vapor pressure
For backward compatibility with Rosemount Rex, the Liquid pressure value can be
remapped to P2 and/or P3. This is done in holding register Sakura_PressConf (1214). If
Liquid pressure is remapped, Vapor pressure will be used for the other pressure requests
that are not remapped.
