27. will always allocate a buffer containing 2049 bytes This is one byte more than previous PACSystems releases To perform a download to the ENIU you must first connect to the ENIU The connect and download functions are now separate in Machine Edition LD Storing a hardware configuration with a new IP address to the RX3i while connected via Ethernet will succeed then immediately disconnect because the RX3i is now using a different IP address than the Programmer You must enter a new IP address in the Target Properties in the Machine Edition Inspector window before reconnecting The default serial protocol for the RX3i is Modbus RTU The default Station Address is 1 If the ENIU is added to a multi drop network care must be taken that the ENIU is configured with a unique Station Address Nodes with duplicate Station Addresses on the same network will not work correctly Care should be taken when timers ONDTR TMR and OFDTR are used in program blocks that are NOT called every sweep The timers accumulate time across calls to the sub block unless they are reset They function like timers operating in a program with a much slower sweep than the timers in the main program block For program blocks that are inactive for large periods of time the timers should be programmed to account for this catch up feature Related to this are timers that are skipped because of the use of the JUMP instruction Timers that are skipped will NOT catch up and will th
