Page 7: About This Manual
MM-IM User Guide About this manual This manual explains how to install, configure and program the Micro Medina Intelligent Modem RTU. It is assumed that the reader has a basic understanding of telemetry, Remote Telemetry Units and configuration of central telemetry systems. The reader may from time to time need to make reference to other manuals in the Master Control set.
Page 8: Other Master Control Manuals
MM-IM User Guide Other Master Control manuals Master Control Getting Started Provides an overview of Master Control: its structure and uses, appearance and terminology. There are basic instructions for using its graphical displays and for navigating the menu structure. Master Control User Guide Instructions for general users of Master Control: how to create and use Summaries and Reports, Trends, Alarms and Events and use additional Commands.
Page 9: The Mm-Im
Additional features such as the provision of independent lower and upper alarm thresholds and time deadbands can be used to reduce the false alarm rate. The MM-IM has been designed to take advantage of mainstream PC technology to reduce costs and allow for easy expansion.
Page 10: Points
Real - Values measured by the RTU at the inputs or Values at the outputs. ■ Derived - Values calculated by the MM-IM internally or used to store data collected from ■ sources other than real I/O (e.g. data from slave RTU’s using the Data Sharing Manager (DSM)).
Page 11 MM-IM User Guide Analogue Inputs Each real analogue point value can be subjected to zero threshold checking that can modify the value. If the value falls below a configurable zero threshold, then the point is considered to have reached its minimum value. The value is then set to the configured zero value.
Page 12: Historic Data
MM-IM User Guide Historic Data The MM-IM will store (trend) points in its memory, providing a history of the site which can be read out remotely by Master Control. Any real or derived analogue input or pulse counter point may be trended. For analogue values, the firmware supports trending of: Current values: the point value at the time the data is written to memory.
Page 13 Remember, without this mechanism for pre-empting the poll schedule, it could be hours or even days before the next scheduled poll goes out to the MM-IM – too long to wait if an alarm condition has occurred.
Page 14 Now all measured analogue signals will exhibit minor variations about a nominal value. This means that as an analogue value approaches one of the setpoints the MM-IM is likely to see a very large number of duplicate alerts being raised and cleared as the value fluctuates about the setpoint level.
Page 15 MM-IM User Guide Alert Level Deadband Hi setpoint t2 t3 Hi Alert: Raised at t = t1 Cleared at t = t3 Figure 2: Alert Level Deadband Example With just time deadband values in place, the current value must now equal or exceed the setpoint value continuously for at least the configured alert time deadband value before the alert is actually raised.
Page 16 MM-IM User Guide Alert Level Deadband Hi setpoint Alert Time Deadband Hi Alert: Raised at t = t2 Cleared at t = t3 Figure 4: Alert Level and Time Deadband Example Each AI is independently configurable and has its own HiHi, Hi, Lo and LoLo setpoints and its own level and time deadband values.

Page 21: Ethernet/Ip
Four different Ethernet/IP configurations are supported, these are: Ethernet/IP Adapter (server) This is used to configure the MM-IM as an Ethernet/IP IO device, to provide data to an Ethernet/IP scanner. IO data is usually grouped into input and output assemblies and read by the scanner at a periodic interval (set by the scanner).
Page 22 N.B. Instance and Class values for input and output assemblies and vendor specific objects should always be in the range 100 to 199. Ethernet/IP Tag Client This is used to configure the MM-IM to read or write tags in a Rockwell Logix5000 series PLC using Ethernet/IP. Ethernet/IP Flex & Point IO...
Page 23: Sequence Monitoring
MM-IM User Guide Further details for the configuring the Ethernet/IP driver can be found in the Straton help files. Sequence Monitoring Timing of the Straton application is monitored and if each cycle starts to take longer, then the Sequence Running Halted error bit will be set.
Page 24 MM-IM User Guide maximum allowed cycle time. The MM-IM will still learn the expected cycle time, but by using a suitable value in the CFG_SWG_LIMIT point, Sequence Running halted errors can be overridden. The common use for this is within applications that have some processing that takes longer only some of the time.
Page 25: Configuration
MM-IM User Guide Configuration The MM-IM configuration can be done in one of two ways — either with or without the Straton-Medina enhancements. With the Straton-Medina enhancements, the entire configuration and file download can be done within Straton. Without the enhancements, both Straton and MicroMC are required.

Medina RTU’s configured as LSI slaves, or from proprietary Medina Bus Master modules. The MM-IM scans the selected serial port when it starts up, to detect any connected slave devices and automatically begins polling. After each polling cycle, it checks for the presence of a new slave device that hasn’t yet been found, in order to achieve “plug and...
Page 35 For integrated inputs, the “size” option can be used to specify a rollover value for the input. This way, the MM-IM works out the increment each time an integrated input changes, and can detect when it rolls over to zero, making use of the full range of the MM-IM’s counter inputs.
Page 36 MM-IM User Guide When the DF1 input rolls over to zero, the MM-IM’s integrated value will increase to 32,768, and continue increasing following further roll-overs. Note: This means that the integrated value presented to the DG will often be different ...

Page 56: Dynamic Configuration And Reporting
This allows each connection to be tested at a suitable rate. The testing relies on the MM-IM needing to dialout to the master (it is irrelevant for an outstation that is only ever contacted by the master). The values relate to the interval at which each particular connection is tested, based on the number of attempted connections.
