setregsl
Set value of signed long integer register
Description
The setregsl function writes the input signed long integer value to the specified Modbus
register. The function writes to two consecutive registers starting at address when the
integer value is written. If the registers are found, their current values are updated. If the
registers are not found, nothing is done.
The validity of the specified Modbus register is not checked. It is assumed that address is an
input or holding register. This function provides a method for accessing database registers
defined in a C Application database handler, such as the RealFLO database handler. This
function may also be used to access the Permanent Non-Volatile Registers. See the section
Modbus Addressing for more details.
