NOTICE!
Availability of parameters described in following chapters depends on
firmware version and the superior parameters they depend on.
8.2.2.1. Mode of operation
Function
- defines module mode of operation in terms of internal functions
and serviced protocols.
The selection controls access to parameters connected with
selected operating mode
Data type

Range
-
MT Slave
module's default setting. In this mode, module answers
GPRS queries addressed to its Modbus ID and sends SMS
and data according to defined Rules but does not relay
queries to PORT2.
Transparent
mode allowing sending GPRS data to PORT2.
Modbus RTU Master
in this mode, the MT-101 module cooperates with external
unit acting as System Modbus Master connected to PORT2.
The module routing table assigns Slaves' Modbus IDs to IP
addresses of their respective GPRS serving nodes in order to
optimize transmission.
Modbus RTU Slave
in this mode, the internal module resources are treated as
resources of the slave with Modbus ID defined during
configuration. Frames received by the module carrying its
Modbus ID are serviced locally while frames carrying other
Modbus IDs are sent to PORT2.
Modem
in this mode, the module acts as GPRS modem controlled by
AT commands. At power on, the module uses PIN code
defined during configuration and logs on to GSM network.
Modbus RTU Mirror
mode enables remote querying of module resources along
with attached units working in Modbus RTU protocol and
event-triggered data sending, as well as creating a mirror
copy of connected units in module's internal registers.
Transparent PLUS
identical with
Transparent
, extended with ability of querying
internal resources and event processing.
GazModem
mode enables cooperation with units connected to PORT2,
using GazModem protocol . MT-101 acts as a local Master
enabling local reading of connected units and alarm
processing. This mode minimizes transmission required to
supervise units. The mode is not supported by standard
firmware and requires firmware marked as MT-
101_x.xxgm.bin.
M-Bus LEC
this mode is dedicated to cooperation with units employing
M-Bus protocol. As in the GazModem mode, the MT module
acts as local master for units connected to PORT2, enabling
readings from central heating nodes. The mode is not
supported by standard firmware and requires firmware
marked as MT-101_x.xxgm.bin.
