Summary:
Upon compiling the project utilising the Mewtocom driver, the following error message came up: "Bad IO Device variable context D000." This is for all addresses between "D0" to "D255". 

Solution:
There is an error in the Driver specification document for this driver and also does Citect help. The correct addressing format for "data registers" is "DTn," not "Dn."
