PlantWatch is an electronic microprocessor-based device that performs the task of supervising a network of Carel instruments. It
manages and records the alarms and the logs of the main values controlled, allowing the data to be transferred via modem to a
service centre. It can also transmit the alarms by fax or SMS and print automatic reports.
Its main use is for the supervision of small and medium-sized supermarkets.
PlantWatch LVQRW a stand-alone DataLogger: it is not fitted with its own probes, but rather reads the values measured by the other
instruments connected to it.

PlantWatch, while featuring functions that can normally be obtained only using a personal computer, is extremely compact and
easy to use. It is a completely independent device, in that its operation does not require the installation of any external device or
software; its own keypad and display allow the fundamental parameters to be set.
Even greater flexibility can be obtained using the options available for the PlantWatch line. The remote connection, fax, SMS
and data centre connection features are available only when PlantWatch is fitted with a modem. There are two possible solutions
in this case: order the version with internal modem, PLW00M0000, or alternatively connect an external PSTN or GSM modem,
using the PLW0PMD000 adapter.
Using the RS485-Printer adapter, PlantWatch can be connected to a parallel printer, which can be located at any point of the
RS485 network that connects PlantWatch to the Carel instruments. The RS485-Printer adapter also performs the function of
network watch-dog.
