NGI-1000/1000RC

Since the introduction of the NGI-1000 users have regularly asked for the possibility to continuously adjust some specific parameters externally. In response to this desire, new features for “Remote Control” are available in the NGI-1000RC version of firmware. Now, for example, it is possible to optimize the ignition timing per cylinder on the basis of detonation (knock) or temperature of the cylinder by a PLC. The new RC-firmware of the NGI-1000 offers the users to continuously adjust several parameters via a Modbus communication and makes it possible to tune the ignition to the engine conditions. With the NGI1000RC firmware the following parameters can be continuously written without impact to EEPROM write cycle durability: n Spark duration (max. 1000 μs) n Spark current (max. 200 mA) n Ignition timing (by new global retard parameter “RMT Global”)(“Default Global”) n Cylinder offset (individual retard “Cylinder-CAL Table”) (“Default Indv”) The parameters mentioned above reside in the RAM memory of the NGI-1000, while EEPROM memory is used only for the default values for these parameters that are loaded by the NGI1000RC when powered on. Impact of the changes In the RC-firmware the Remote Control parameters have been incorporated into the Modbus register list. Some other parameters were replaced or removed compared to the original firmware. The new parameters have a logical place in the register list in order to minimize the number of read/write commands. As a result a number of tables that also exist in the original firmware have different register numbers in the RC firmware version. For this reason, the original NGI-1000 as well as the NGI-1000 with RC are now both available for purchase. Module Part numbers ending in “RC” will be equipped with latest Remote Control firmware. While we expect the “RC” version to become the new standard; support of either option is provided through a new and separate revised RC terminal program as well as a new separate operation installation manual which can be referenced to both study and exercise these new RC features.
