2.5.3.1Description of PMC6

In register 2400, a plain text ASCII description of PMC6 is given

Start	Number of	Reg1 … Reg8	Modbus	Read	Write
register	registers	16 ASCII characters	function code	access	access
2400	8	Description of PMC6	3, 4	U/A/S	none

Figure 2.5.3.1.1: Definition of register 2400.

Command: PMC6 text			Modbus address: 2400		Length: 8	Type: 3	Read
Parameter:	Text
Format:	Character
Value:	T

Figure 2.5.3.1.2: Example to read the description. It is “T”(Temperature).

2.5.3.2Selecting the Physical Unit for PMC6

In register 2408, the available physical units of PMC6 are defined.

Start	Number of		Reg1 / Reg2				Modbus		Read	Write
register	registers		(bitwise defined)				function code		access	access
2408	2		Available physical units of PMC6				3, 4		U/A/S	none
Figure 2.5.3.2.1: Definition of register 2408.

Command: PMC6 available units					Modbus address: 2408		Length: 2	Type: 3		Read
Parameter:		Units
Format:		Hex
Value:		0x06

Figure 2.5.3.2.2: Example to read the available physical unit for PMC6. K (0x02) + °C (0x04), total 0x06.

In register 2410, the active physical unit of PMC6 can be selected, by choosing one of the physical units that are defined in register 2408.

Start	Number of	Reg1 / Reg2	Modbus	Read	Write
register	registers	(bitwise defined)	function code	access	access
2410	2	Selected active physical unit of PMC6	16	none	U/A/S

Figure 2.5.3.2.3: Definition of register 2410. Only one bit can be set.

Command: PMC6 set unit			Modbus address: 2410		Length: 2	Type: 16	Write
Parameter:	Unit
Format:	Hex
Value:	0x04

Figure 2.5.3.2.4: Example to set the physical unit of PMC6 to °C (0x04).

Attention:

Changing the physical unit has also an influence on the output of AO1 / AO2, as the same physical unit is active for the analog outputs. All limits of the 4-20 mA analog output have to be redefined after changing the physical unit!
