    2.7 Applying power for the first time Once the T2 CPU has been installed into a Maxiflex rack, apply power and the CPU OK LED will turn ON and remain steady ON until power is removed. If the CPU OK LED remains OFF, then check the power connections to the PSU module and that the LED indication of the PSU module is normal.
  • Page 14 (refer to Section 4. Installation). If the jumper appears to be correct and the BATT LED is still ON, then the battery level is low and the battery needs to be replaced. Please consult your OMNIFLEX distributor to arrange battery replacement. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

    3.2.2 I/O Scanning This function is responsible for the scanning of conventional I/O modules installed on Maxiflex base, sorting the data into convenient tables according to type of I/O (Analogue or Digital; Input or Output) and reading/writing this data to/from the CPU’s Data Interchange Table (DIT) for easy access from any of the network ports.

    3. Ensure the correct COM port is selected in OMNISET. (DITview uses a different method via the CONET server. See the help for this product for further information.) 4. Open the template file named “011001nn(M124xA).dvx” supplied with OMNISET. (The nn is replaced with the revision number of the latest available dvx file).

    4.3 Addressing a Module through the Programming Port The first step when starting to configure a module in a Maxiflex System with a T2 CPU is to select the address of the module. In Omniset, select the module to be addressed as follows: From the pull-down menu select “Remote”, then “Target Address…”.

  • Page 20: No Address Set

    Global Addresses (in the range 127 to 254). Use this option to select any target node in the system using its Global Address. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

  • Page 21: Configuring The Real-Time Clock

    To select this mode, switch SW7 and SW8 of the serial port address switch to OFF. Switches 1 to 5 of the DIP switch set the communications address used to access the T2 CPU through this serial port. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

  • Page 22: Modbus Data Register Mapping

    The standard layout of the Data Interchange Table provides 4000 registers for each Module Slot on a Maxiflex base (see section 5.1). Some Modbus Master devices are pre-programmed with a maximum allowable range of 10,000 holding registers. This makes it impossible to access the DIT registers in I/O slots from Slot 3 onwards (DIT addresses 12,000 upwards).

  • Page 23: Conet/S (Peer-To-Peer) Protocol

    Consult the factory for available protocols, or for assistance in writing your own protocol in EZIFORTH. In this mode, the configuration switches 1-5 are unassigned by the T2 CPU, and may be used by the custom serial protocol software downloaded.

    Writing to this area of the DIT is slower than accessing the Dynamic DIT area, and continuous writing to this area during normal system operation should be avoided. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

  • Page 28: I/O Module Management & Scanning Explained

    6. I/O Module Management & Scanning Explained The T2 CPU automatically identifies the I/O module types installed in a Maxiflex system. This information is used for two purposes: 1. Checking of the presence of the correct I/O modules in a system.

  • Page 29: Checking The Status Of Installed Modules

    CPU’s dynamic data area is the fastest area to read/write. The table below identifies the DIT register locations in the CPU’s Dynamic Data Area of the DIT where the I/O scanning stores/retrieves its data. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

    5. Analogue Modules are scan rate = (10.n + 10) milliseconds, where n is the number of analogue modules installed on the Master and Expander Bases. Eg 3 installed analogue modules will be scanned every 40ms, 15 Ananlogue modules will be scanned every 160ms. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

  • Page 31: The Subscription Service Explained

    It also limits the number of master nodes in the system to one. The Maxiflex T2 CPU provides a far superior mechanism to accomplish this commonly used function through its Subscription Service. This Service operates as follows: The node requiring the data sets up a subscription with the source node, very much like you would subscribe to a magazine through your newsagent.
  • Page 32 The “sink” node then automatically manages the subscription including sending the requests to the data source, and managing errors in the process. Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...

  • Page 33: Number Of Subscriptions Allowed

    In other words each T2 CPU can act as data sink for 32 subscriptions, and data source for 8 subscriptions simultaneously. 7.4 Subscription Application Example Refer to the diagram of a simple network below: Node Address 2 Node Address 5 Node 2 subscribes to data from Node 5 CONET Maxiflex T2 CPU User Manual -© Omniflex UMM124XBR04.pdf...
