Added exception code Reprogrammed Refused 06 ii. Elektronikon MkIV Modbus 1. The Physical set-up 1. This is done according the Compressor Network Cabling Instruction. Basically this is a CAN-based local network. In order to setup a modbus connection to one or several of the compressors in this network, a special module as to be inserted in this network. This module will then behave as a modbus-proxy that allows access to all compressors in the network, whereby each compressor has its own modbus address proxy concept.
This proxy-conversion table has to be set with proper tools. This is a general purpose serial communication module. By downloading the correct software in it, it will perform the modbus proxy function. For modbus the following will be used 10x Network Modbus Network – 8. Before installation check the available power of the 24Vac transformer, if connecting to an already supplied transformer inside a cubicle LED s The module also has a number of LED s on type.
They are used as follows: Modbus receive Combox receives Modbus message 6. Modbus transmit Combox transmits Modbus message 7. Before powering the Combox S module, check all cables. Modbus protocol implementation 2. Frame synchronization in the RTU mode is done by simulating a synchronous message.
The slave maual monitors the elapsed time between receipt of characters. If three character time elapsed without a new character, then the device assumes that the message is completed and the next byte will be the address The message frame format is following: When there is bad communication, only the detailed general compressor condition will be set to. Each input has a value and a status register assigned.
The contents of these registers depend on the actual type of sensor that is connected.
This can be different for every type of compressor. Before using the modbus system it is therefore required to find out what sensors are really connected to your compressors. Once the list of sensors is known, the contents of the registers can be interpreted as described below Registers Sensor Inputs Function to be used: Each part bit of the data byte is indicating a specific item that applies on the Input function.

In the following table, an overview is given of all bits together with the corresponding meaning and interpretation. On some high pressure compressors with working pressures above 30 bar a special Pressure Input can be defined that returns data in cbar 0.
Maunal values cannot be negative. The contents of these registers is for digital inputs always the same, if the input is used. Before using the modbus system it is therefore required to find out what inputs are used on your compressors. Once the list of inputs is known, the contents of the registers can be interpreted as described below. Function to be used: Each input as 2 x 16bit value register assigned, to allow a bit value to be read.
Not all eelktronikon of compressors use all types of counters. Each such counter as 2 x 16bit value mannual assigned, to allow a bit value to be read. Only units where the MCC master function is active contain real data for this registers. Read Holding Register 03 Modbus registers Information unit Compressor 1 counter s Compressor 2 counter s Compressor 3 counter s Compressor 4 counter s Data interpretation is the same as for the other counters.
Read Holding Register 03 Modbus registers Information unit Required motor speed rpm Actual motor speed motor 1 rpm Actual motor speed motor 2 rpm Actual manuak speed motor 3 rpm Each register contains a bit value that is directly readable as the equivalent rpm. Read Manuxl Register 03 For writing: Unloading pressure should not be above the maximum setting that was factory defined.

Values not fulfilling this will be refused VSD Setpoint change It is possible to change the operating set point inside the Elektronikon MkIV, or to switch between the two available pressure set points. These registers are only valid for VSD compressors For reading: Values not fulfilling this will be refused by the MKIV.
Functions to be used: The number of sub-types is different for each main type. This has to be done through the display, select LAN Control.
By default the compressor will then enter the 4a mode. Through Modbus it is now possible to activate the other sub-types. Carefully consult the control concept of the compressors before using them.
