*These addresses have already been changed to the absolute form required 
for EZwarePlus by adding 1 to the value listed in the Watlow manual. Enter 
them as listed.
•  For Destination address PLC name choose the OIT (“Local HMI” by default). 
•  For Destination address device type choose LW. 
•  In Destination address Address type the local address at which to save the data to be logged. 
Note: Pick a range of addresses with room to store all the data that must be displayed. For example, use 
200 for the first parameter to be logged then for each additional parameter increment the address by 
the size in words of the previous data. For example, typically you log floats such as process 
variables and set points which each require two words to store. In that case if the first process 
variable is copied to 200, set the next parameter to copy to 202 so on. In this example, a process 
variable, a set point and the heat output power are logged.
