(cr)
Example command: $0A4(cr)
response:
Presume the present output value of the analog output
module at address 0A is 9.4 mA. The command tells the
analog output module to store the present output value into
non-volatile memory. When the module is at start-up or
reset, its default output value will be 9.4mA. The response
of the analog output module indicates that the command
has been received.
NOTICE: An analog output module requires a maximum of 6 milli-seconds
after it received a Startup Voltage/Current Output Configuration
command to let the settings take effect . During this interval, the
module can not be addressed to perform any other actions.
