6.12. ES851 DATALOGGER BOARD (SLOT B)
ES851 DataLogger is an option board allowing acquiring the operating variables of a plant and interfacing to
a supervisor computer, even a remote computer, through different connecting modes for data logging and
monitoring of the devices connected to the plant.
The main features of the DataLogger are the following:
- 8-Mb Data Flash, allowing setting how many variables and which variables are acquired, as well as
their acquisition time, for optimum performance of the available memory;
- RS485 and RS232 interface with Modbus-RTU protocol;
- Ethernet interface with TCP/IP protocol;
- Interface for the connection via GSM modem and analog modem;
- SMS functionality for events monitored by the DataLogger (available only when a GSM modem is
used).

Each DataLogger is capable of monitoring up to 15 devices through RS485 or RS232 network with Modbus
protocol. ES851 is the master and the connected devices are the slaves.
A remote computer can be connected to the plant via RS485 or RS232 serial links, via modem or via Ethernet.
The RemoteDrive software allows performing any operation both on the plant devices and on ES851 (scanning
the devices connected to the DataLogger and activating data acquisition except for the devices excluded from
logging—see the Programming Instructions of ES851 DataLogger for more details).
The connection modes and specifications are detailed in the following sections.
