CH1 PV value
The PV value of the used HART-enabled device is stored in 32-bit floating points.
■Stored value
• The PV value differs depending on the HART-enabled device. For details on the stored values, refer to the manual of the
used HART-enabled device.
• The unit of the stored PV value can be checked in 'CH1 HART device information (PV engineering unit)' (Un\G2567).
• When there is no variable corresponding to the PV value in the used HART-enabled device, 7FA00000H is stored in this
area.
• When the HART communication function is not used, 7FC00000H (default value) is stored.
■Refreshing cycle
The stored status information is automatically refreshed every HART cycle time.
■Buffer memory address
The following shows the buffer memory address of this area.

CH1 SV value
The SV value of the used HART-enabled device is stored in 32-bit floating points (single-precision real number).
■Stored value
• The SV value differs depending on the HART-enabled device. For details on the stored values, refer to the manual of the
used HART-enabled device.
• The unit of the stored SV value can be checked in 'CH1 HART device information (SV engineering unit)' (Un\G2568).
• When there is no variable corresponding to the SV value in the used HART-enabled device, 7FA00000H is stored in this
area.
• When the HART communication function is not used, 7FC00000H (default value) is stored.
■Refreshing cycle
The stored status information is automatically refreshed every HART cycle time.
