Basic Notions
Z-GPRS2/Z-Logger is equipped with 4 counters and 4 totalizers. Up to a maximum of 30 Hz signals
can be acquired, 4 digital inputs, 2 analog inputs and 2 relay digital outputs.
Z-GPRS2 I/O and remote Modbus RTU or Modbus TCP-IP registers can be logged and sent as a file
in csv format (comma separated values) via ftp or email and saved on microSD. Z-GPRS2 can also
send the last row of the log file via SMS.
Counter and totalizer overflow is 999,999,999. An additional input status change switches the
value to 0.
Up to 11774 log rows can be saved in the internal flash memory (not to be confused with the
microSD card), If all 100 TAG modbus is activated only 2943 log rows can be saved on internal
flash. At the end of available space, Z-GPRS2/Z-Logger overwrites the oldest rows in the memory.
Counter/totalizer inputs and analog inputs can be scaled. The scaled values will be saved in the
log.
4 different alarm thresholds are available for each of the two analog inputs. An SMS (only for Z-
GPRS2) or EMAIL can be sent with a settable text when this alarm trips (max 31 characters).
Other types of alarms concern counters, totalizers, digital input increases, power outage, plumbing
leaks and the hour counter in addition to other alarms that depend on the type of application.
Up to 2 different actions can be set and run as a consequence to an alarm.
NR 10 minute/hour or calendar timers are available to run cyclic or acyclic actions.
Z-GPRS2 recognises and runs a series of commands also via SMS. A set of "FAST" commands can
also be set. These commands can be linked to the text in SMS 0, 1 up to 15.
Z-GPRS2/Z-LOGGER can send log files via FTP or via E-MAIL. These files can also be saved on
microSD or microSDHC (max 32 GB).
All configurations are possible via Easy Setup/Easy Z-GPRS2/Z-Logger software, available for free
download at www.seneca.it in the download or Z-GPRS2 / Z-LOGGER section.
