Yokogawa|CTL4*B| Ratio Parameter
YOKOGAWA CTL4*B CT Ratio Parameter (Software Register)
The YOKOGAWA CTL4*B refers to the lower two bytes of the Current Transformer (CT) ratio setting for address 4 in YOKOGAWA power monitoring devices operating under Profile 201 (Data Monitoring Mode).
Features
- Part of CT ratio configuration for phase or circuit #4
- Stored as a 4-byte IEEE floating-point value split into CTL4 (low) and CTH4 (high) registers
- Configurable via RS485/DeviceNet using ND210 converter
Technical Specifications
- Register Name: CTL4 (lower word of CT ratio for address 4)
- Paired with: CTH4 (upper word) to form full 32-bit IEEE 754 float
- Data Type: 4-byte floating point (IEEE standard)
- Access Method: Write to OUT AREA channels 0–F (HEX) in Parameter Setting Mode
- Addressing: Power monitor address set in upper nibble of F channel; parameter count in lower nibble
- Communication Protocol: Profile 201 over DeviceNet/RS485 via ND210 converter
- Write Procedure:
- Confirm End of writing flag = 1
- Set Write request flag (bit 4 of 10h in OUT AREA) to 1
- Clear flag after End of writing returns to 1
- Apply Re-setting flag (bit 0–3 of 11h in OUT AREA) for at least 1 second
