The following examples show the use of the SE message for multiplexer
control:
SE M_C,Y
Y sets the Monitors to be multiplexer system
controller.
N sets the Monitor not to be system controller.
SE U_CH,1,Y
Activate Multiplexer channel 1.
N Deactivates Multiplexer channel 1.
SE? U_CH,1
returns Y or N for use of the defined channel.
SE? U_CH
returns a list of activated channels.
i.e.
1,1,2,1,3,1,4,0,5,0,(etc. up to),24,0
Channel 1, 2 and 3 are in this case activated.
The following examples show the use of the SE message for Analog output
and Relay output setup:
SE A_U,U_4_20MA_PPM
Setup the Analog unit to 4-20 mA / ppm
SE? A_U
Returns the Analog unit
SE A_MI_C,F_A,100.0
Setup the Analog minimum concentration for Filter
A to the value 100
SE A_MA_C,F_A,1.0E3
Setup the Analog maximum concentration for Filter
A to the value 1000
SE A_MA_C,F_A,1E32
Resets the Analog maximum concentration for
Filter A
SE A_R_C_M,Y Activates the Analog relay channel mode
SE A_R_N,1,2
Setup Alarm limit exceeded on Multiplexer channel
1 to activate Relay 2 on the Analog & Relay output
module.
SE A_R_N,1,__ (or 65535)
Setup Alarm limit exceeded on Multiplexer
channel 1 to not activate any Relays on the Analog
& Relay output module.
