The Geo SCADA Expert SCADAPack Modbus Driver supports several Modbus function codes, enabling it to read and write data on SCADAPack devices. The standard function codes that the Geo SCADA Expert SCADAPack Modbus Driver supports are the same as those that are supported by its 'parent' Advanced Modbus driver (see Modbus Function Codes Supported by the Geo SCADA Expert Advanced Modbus Driver in the Geo SCADA Expert Guide to the Advanced Modbus Driver):
