@AACCCSDMTTTT
Name Set Memory Configuration
Description Sets the channel storage status, standalone mode, data logger
mode storage type and sampling interval for the specified
analog input data logger.
Syntax @AACCCSDTTTT(cr)
@ is a delimiter character.
AA (range 00-FF) represents the 2-character hexadecimal
address of an analog input data logger.
C identifies the Set Memory Configuration command.
CC (range 00-FF) represents the data storage status of each
channel. The ADAM-4018M has 8 channels, bit 0 representing
channel 0, and bit 7 representing channel 7. A mask bit value
of ‘1’ enables data storage in the specified channel, while a
mask bit value of ‘0’ disables data storage.
Channel 7
Channel 0
S represents the standalone mode. In order for the ADAM-
4018M to operate in the field, you must power on the memory
module by setting this value to ‘1.’ Otherwise, the data will not
be recorded.
D represents the data logging mode. ‘0’ enables Standard
Mode, where all eight channels record the normal data accord-
ing to the sampling interval. ‘1’ enables Event Mode, where all
eight channels record the data if its value is over the High
Alarm limit or under the Low Alarm limit. ‘2’ enables Mixed
Mode, where channels 0 - 3 act as the standard logger and the
channels 4 - 7 act as the event logger.
M represents the storage type. "0" represents writing to the
end of memory. "1" represents circular memory mode.
TTTT (range 2-65535) represents the sampling interval in
seconds.
(cr) is the terminating character, carriage return (0Dh)
