  • Page 22: Section 2 Ths 2000 Software Program

    The THS 2000 software is designed to allow a direct connection (via RS-232, RS-422 or RS- 485) to Port 2 of the CIM or a remote connection (via a host PC modem) with the internal modem of the CIM on Port 1. The host PC modem must already be configured before attempting a remote connection.

  • Page 23: Improvements

    THS2000 version 3.1 adds the ability to connect directly to an RTU, bypassing the CIM. A maximum of one RTU, MEC20 or TSC800, is allowed. The auto-answer feature of THS2000 is not supported in this mode, as it is a function of the CIM. The auto-discovery of controllers is likewise not available. See...

    Once the connection method is established, you will be prompted for the site properties, such as site name, as shown below. This allows you to enter the first site in the site-list. The name and password fields correspond to the name and password already programmed into the CIM that is managing the remote site.

  • Page 34 SECTION 2 THS 2000 SOFTWARE PROGRAM normal operation for the CIM is to poll the status of each controller and attempt to discover new controllers. When the status of a controller indicates an alarm condition, the CIM can be programmed to call the host and report that an alarm condition exists.

When the mouse pointer is floated over the tool item, a tool tip is displayed in the status line portion of the status bar. 4.1.6. Controller Bar The controller bar contains a button called List and a button for each controller on the site.

  • Page 47: Connecting Sites

    A site is made up of a single CIM connected to one or more controllers. Connecting to a site is the same as connecting to a CIM. From the user’s point of view, the CIM is the site. This section describes how sites are connected and disconnected as well as various properties of the CIM and the host connection.

During this time, the operator can view the controllers and determine the cause of the alarm. The status bar will also display a countdown of the remaining connection time in seconds.

    Port 2 (DB-9 or RJ-45) which is configurable to RS-232/-485/-422 and up to 19200 baud. The MEC 20s or TSC 800s connect to the CIM (Host) through an RS-422 interface via an RJ-45 connector to CIM port 3b. Up to 10 remotes can be connected to a single CIM (Host), as shown below:...

  • Page 55: Datalink Layer

    The CIM acts like a local host (master) to the MEC 20's connected. The CIM takes care of gathering data from the individual MEC 20's and storing it in a local database. The communication format describes an interface with the CIM database.

  • Page 56: Preset Multiple Registers (Type 16)

    Unfortunately due to processing limitations response packets from the CIM to the host can have up to 25ms gaps in the data. The CIM response data is shifted out in 16 character increments, in some cases it can take up to 25 ms to shift out the next 16 character buffer.

    SECTION 3 CIM PROTOCOL It is also recommended to follow up with a Display Valid Flag read to insure the operation was successful before proceeding. The CIM does attempt multiple operations in the case of a bad packet. However, if the Display Valid Flag is not valid after 900ms a retry should be performed.

  • Page 59: Application Layer

    CIM communication is done with the same Modbus packet using the CIM ID instead of the MEC 20 ID. In the case of the same ID the CIM is smart enough to look at the registers requested to figure out whether it is meant for a CIM or MEC 20.

  • Page 60: Data Types And Formats

    The following table describes the possible return data types and formats for Modbus registers defined in the CIM. A register data value consists of two bytes: the most significant (MSB) and the least significant (LSB). Data values are arranged with the MSB first (called big-endian).
