CHAPTER 1: COMMUNICATIONS INTERFACES MM200 MOTOR MANAGEMENT SYSTEM – COMMUNICATIONS GUIDE...
RS485 hardware. Using RS485, up to 32 MM200s can be daisy-chained together on a single communication channel. The MM200 is always a Modbus slave. It can not be programmed as a Modbus master. Computers or PLCs are commonly programmed as masters.
Data Frame Format and Data Rate One data frame of an asynchronous transmission to or from a MM200 typically consists of 1 start bit, 8 data bits, and 1 stop bit. This produces a 10 bit data frame. This is important for transmission through modems at high bit rates (11 bit data frames are not supported by Hayes modems at bit rates of greater than 300 bps).
CHAPTER 2: RS485 INTERFACE (MODBUS RTU) MODBUS PROTOCOL If a MM200 Modbus slave device receives a transmission in which an error is indicated by the CRC-16 calculation, the slave device will not respond to the transmission. A CRC-16 error indicates than one or more bytes of the transmission were received incorrectly and thus the entire transmission should be ignored in order to avoid the MM200 performing any incorrect operation.
Modbus implementation: Read Holding Registers MM200 implementation: Read Setpoints For the MM200 implementation of Modbus, this function code can be used to read any setpoints (“holding registers”). Holding registers are 16 bit (two byte) values transmitted high order byte first. Thus all MM200 Setpoints are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.
Modbus Implementation: Read Input Registers MM200 implementation: Read Actual Values For the MM200 implementation of Modbus, this function code can be used to read any actual values (“input registers”). Input registers are 16 bit (two byte) values transmitted high order byte first. Thus all MM200 Actual Values are sent as two bytes. The maximum number of registers that can be read in one transmission is 125.

For example, consider a loopback test from slave 17: Table 2-7: MASTER/SLAVE PACKET FORMAT FOR FUNCTION CODE 08H...
CRC error code Error Responses When a MM200 detects an error other than a CRC error, a response will be sent to the master. The MSBit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128).

No connection CNTR-N Repeater control 1.The MM200 can accept an external voltage level up to 24VDC on its V- and V+ terminals. Note that specifically for termination, the voltage must be reduced to 5V; refer to the Profibus Termination section below.
The MM200 relay supports mandatory parameterization. The relay keeps its user parameter data / setpoints in non-volatile memory and does not need device related parameterization during startup of the DP master. The EnerVista MM200 Setup software is the best tool for user parameterization of the MM200 device.
The end nodes on a Profibus-DP network must be terminated to avoid reflections on the bus line. The Profibus bus address (MAC ID) of the MM200 slave, which has a range from 1 to 126, can be set via the EnerVista MM200 Setup software. Address 126 is used only for commissioning purposes and should not be used to exchange user data.
Page 39
When a size of input data smaller than the maximum is configured, the data read from the MM200 by the master will start at address 0 of the Profibus Input Data table (refer to section 4.4.4) and provide data in the order shown in that table, up to the size configured.

CHAPTER 3: FIELDBUS INTERFACE Figure 3-8: Profibus - no extended diagnostic data Profibus DPV1 The MM200 relay also supports DPV1 extensions. The device supports Class 1 and Class 2 acyclic reads and writes as well as DPV1 Diagnostics. Profibus DPV1-Acyclic read/write data The motor status data can be read acyclically by retrieving the byte lengths indicated below from the relevant Object, Slot, Index.
The MM200 memory is mapped in 16 bits variables, thus, only communication data exchange with even data quantities is accepted. The security functionality implemented on MM200 is strictly applicable. Parameter write access is controlled by passwords as defined in Security Section of the MM200 Instruction Manual. Acyclic Read...
The extended diagnosis consists of Process Alarms and Diagnostic Alarms. Trip, Alarm, and Control status are categorized as Process Alarms, as these provide information pertaining to the Motor health that MM200 is controlling and monitoring. Messages are categorized as Diagnostic Alarms as these provide detailed MM200 diagnostic information.

DEVICENET PROTOCOL CHAPTER 3: FIELDBUS INTERFACE Click the double arrow (>>)to move the MM200 from the Available Devices list to the Scanlist. Select Major Revision as the part of the electronic key for MM200. Double-click MM200 in the Scanlist. The Edit I/O Parameters dialog (shown below) appears for the MM200.
In the MM200, only the contents of the A1 object are supported by ADR. Enabling ADR Before proceeding to the next step ensure that the MM200 relay and the network are NOTE: configured as desired. These configurations will be then stored in the scanner for the ADR feature.

Page 79
So always remember to UPLOAD the MM200 configuration into the RSNetWorx and SAVE the file before enabling ADR. The MM200 does not support auto baud detection. So in a situation where the faulted device is replaced with a new device with default settings, ensure that the baud rate of the MM200 is the same as that of the scanner.
DEVICENET PROTOCOL CHAPTER 3: FIELDBUS INTERFACE Considering the scanner’s limited memory for storage of the ADR configuration, more than one scanner will be required if there are many MM200 relays in the DeviceNet network.
