7.3.8. DIGITAL INPUT: PULSE COUNTER
The functions 0x04 and 0x10 are implemented for this variable.
If the Digital Input has been configured as Pulse Counter, the value of the counter is displayed in this
variable.
Table 77:Modbus memory map: Pulse counter.

Variable Format Address
Digital input pulse counter Uint [64] 4E23 - 4E24 - 4E25 - 4E26
7.3.9. DEVICE CONFIGURATION VARIABLES.
The functions 0x04 and 0x10 are implemented for this variable.
The device’s Modbus function does not check whether the variables recorded are within the correct
margins, they are only checked when they are read from the EEPROM. So if any parameter is recorded
with an incorrect value the device will be configured with its default value.
The Modbus configuration will not take effect until the device is reset.

Configurable parameter in the models: CVM-E3-MINI-ITF, CVM-E3-MINI-ITF-WiEth, CVM-E3-MINI-MC and CVM-E3-
MINI-MC-WiEth.

Configurable parameter in the models: CVM-E3-MINI-ITF and CVM-E3-MINI-ITF-WiEth.
Note: The ratio is between the primary and the secondary.
Note: The 5 registers must be written or read at once (as a group); otherwise. the system will respond
with an error.
