Modbus to HART Gateway Installation
Wiring
Dimension of G0310 MODBUS to HART gateway is 99×22.5×114.5mm, supporting standard DIN guide rail installation.
The power supply of G0310 MODBUS to HART gateway is HART bus, and 485 communication need external 24V power supply. The recommended is TP cable, and it shall improve device’s anti-electromagnetic interference ability.
Modbus to HART Gateway Jumper configuration
G0310 MODBUS to HART Gateway has 2 jumpers, as shown on picture.The left one is failure warning current setting and the right one is configuration protection setting jumper.
G0310 Modbus to Hart Gateway Jumper
Failure Warning Jumper Setting
G0310 MODBUS to HART Gateway has self-diagnostic function. Once failure is found, intelligent instrument will output warning current automatically. Warning current mode is decided by failure warning current jumper on the left of the board. When there’s no insertion or insertion of two points underside, it’s high-level warning (warning current≥21.75mA)；When it’s the insertion of two points upside, it’s low-level warning (warning current≤3.7mA).
Configuration Protection Jumper Setting
G0310 MODBUS to HART Gateway provides jumper setting of device configuration protection or not, that is the configuration protection setting jumper described above, as shown on figure 3. When it’s the insertion of two points upside, it’s configuration protection. At this moment no change of device configuration is allowed. It is allowed when there’s no insertion or insertion of two points underside.
Saturation fixed output (manufacturer setting, no configuration)
When HART intelligent instrument is running, it will compare PV and range upper and lower limiting value constantly. When PV exceeds the limit, instrument will output fixed current. When PV is higher than upper limit, it output 20.8mA；When PV is lower than upper limit, it output 3.8mA.
Working Principle
