 +==== SetReg(variable_name[,connection_name], new_value) ====
 +The SetReg function sets the current value of the register with the name of the variable **variable_name** to **new_value** for the current scan. This function **DOES NOT** send new value to external devices. When polling this register in subsequent cycles, the old value will be read. 
 +
 +Function returns 1 if an error occurred and 0 on success.
 +
 +The parameters **variable_name** and **connection_name** work just like in the GetReg function. Since version 3.2 there is no more **connection_name** parameter.
 +
 +
 +==== WriteReg(variable_name[, connection_name], new_value) ====
 +The WriteReg function sets the current value of the register with the name of the variable **variable_name** (optionally you can specify the connection **connection_name**) to provided **new_value** for the current scan and writes this value to the external device in the beginning of the next cycle. When polling this register in subsequent scans, a new value will be read (if it was not changed by the device itself). 
 +
 +Function returns 1 if any error occurred and 0 on success.
 +
 +The parameters **variable_name** and **connection_name** work just like in the GetReg function. Since version 3.2 there is no more **connection_name** parameter.
