However, if there are special SIOX modules connected to the bus, i.e. modems or radio modules, extra timeout may be added to compensate for the delay in these units.
Page 12 = Last modbus slave address assigned for SIOX. Addresses above this number are on Modbus RTU and addresses less than or equal are on SIOX. A value of 0 or greater than 247 will set it to 255. That means all addresses can be used by the SIOX bus.
