2.5.2.3Reading the measurement value of PMC1

Register 2090 is also used to read the measurement values of PMC1.

Figure 2.5.2.3.1: Definition of register 2090. Measurement value of PMC1.

(1)Value is always in the physical unit defined in register 2090.

(2)Definition of the status see chapter 2.5.4. All bits set to zero means: no problem.

Command: PMC1 read			Modbus address: 2090		Length: 10	Type: 3		Read
Parameter:	Unit	Value		Status	Min limit		Max limit
Format:	Hex	Float		Hex	Float		Float
Value:	0x1000	4.02503		0x00	0		14

Figure 2.5.2.3.2: Example to read register 2090. Physical unit is set to pH (0x1000), PMC1 is pH 4.02503, Status is 0x00, Min allowed value is pH 0, Max allowed value is pH 14.

Command: PMC1 read			Modbus address: 2090		Length: 10	Type: 3		Read
Parameter:	Unit	Value		Status	Min limit		Max limit
Format:	Hex	Float		Hex	Float		Float
Value:	0x200000	175.9922		0x00	0		954.6541

Figure 2.5.2.3.3: Example to read register 2090. Physical unit is set to mV (0x200000), PMC1 is 175.9922 mV, Status is 0x00, Min allowed value is -414.0028 mV, Max allowed value is 414.0028 mV.

For the definition of the measurement status see chapter 2.5.4.

Attention:

You cannot read selectively the registers 3 and 4 for the measurement value only. You have to read the entire length of the command (10 registers) and extract the desired information.
