PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Diagnostics and Troubleshooting Removing Timing Marks in the Data Analyzer Press [0] to turn off timing marks in the Data Analyzer screen. Viewing Data in Hexadecimal Format Press [H] to display the data on the current page in hexadecimal format. Viewing Data in ASCII (Text) Format Press [A] to display the data on the current page in ASCII format. This is useful for regions of the database that contain ASCII data.
Diagnostics and Troubleshooting PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Important: When in analyzer mode, program execution will slow down. Only use this tool during a troubleshooting session. Before disconnecting from the Config/Debug port, please press [S] to stop the data analyzer, and then press [M] to return to the main menu. This action will allow the module to resume its normal high speed operating mode. Returning to the Main Menu Press [M] to return to the Main Menu. 7.1.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Diagnostics and Troubleshooting After you have selected the Port, Format, and Tick, we are now ready to start a capture of this data. The easiest way to do so is to go up to the top of you HyperTerminal window, and do a Transfer / Capture Text as shown below: After selecting the above option, the following window will appear: Next name the file, and select a directory to store the file in. In this example, we are creating a file ProSoft.

Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Master Specifications A port configured as a virtual Modbus Master device on the PTQ-MCM module actively issues Modbus commands to other nodes on the Modbus network. One hundred commands are supported on each port. Additionally, the master ports have an optimized polling characteristic that polls slaves with communication problems less frequently.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference The module transfers the entire read and write areas at the end of every processor scan. The module will hold the processor scan for a certain period of time, which allows the module to transfer the entire read and write areas. This means that the larger the read and write areas, the longer the processor scan time will be. Refer to Module Performance for more detailed information on determining scan times.
Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module The parameter fields in the block should be completed as required by the selected function code. Each command has its own set of parameters. When the block is received, the module will process it and place the command in the command queue.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference Note: Command Control blocks are not copied to the module database. You must define variables in the module's main memory, and use processor logic to process the command control request.
Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Command Control Word Description 30004 Block response word 2 30005 Block response word 3 … … 30064 Block response word 62 The module recognizes that there is a new block request when it identifies that the block sequence number has changed. if the block ID is valid, the module will process the block and copy the response to the input command control area (3x for Quantum / Unity or %IW for Unity).
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference Blocks in the range of 5001 to 5006 are used for Port 1, and blocks in the range of 5101 to 5106 are used for Port 2. The last digit in the block code defines the number of commands to process in the block. For example, a block code of 5003 contains 3 command indexes that are to be used with Port 1. The Command index parameters in the block have a range of 0 to 99 and correspond to the master command list entries.
Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module 8.2.7 Pass-Thru Control Blocks Overview Caution: This feature allows a remote modbus master to directly update the processor memory. The user should carefully read this section before considering this feature in order to avoid transferring data to unexpected memory areas in the Quantum processor.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference The following illustration shows the three basic steps performed during the passthru operation. Quantum PTQ- MCM 3 1 2 Modbus Master The module receives a modbus write command. For example: 1 2 3 4 5 6 Modbus Function: Preset Multiple Registers (function 16) Count: 10 words Destination Address: 500 The module verifies that the destination address is a valid address in the processor.
Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module The following flow chart show the implementation of the direct pass-thru block: Receive write command. Is the destination address valid? N Send response with Invalid Address exception. Y Attempt to write command to backplane queue. Send response with Slave Busy exception. N Is there an available space in the queue? Y Add to backplane command queue. Send normal response. Wait for next command.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference Both ports can operate in pass-thru mode simultaneously. If the port is configured for pass-thru swap the module will swap the data bytes (high order/low order) before transferring the data to the processor. Since the module transfers the data directly to the processor the PTQ-MCM database is not updated during pass-thru operation.
Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Block Pass-Thru Control Blocks If one or more of the slave ports on the module are configured for the block passthrough mode of operation, the module will pass blocks with specific identification codes to the processor for each received write command. Any Modbus function 5, 6, 15 or 16 commands will be passed from the port to the processor.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference In this example, the following variables are used: Variable BlockID Address 401001 Type INT BlockData 401004 WordArr128 Mask 401054 WordArr128 DestinationData Any WordArr128 Description Variable that contains the block ID. When this value is equal to 9959 the processor will trigger the logic to handle the pass-thru block.

Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module The addressing allows up to 2000 coils to be obtained at each request; however, the specific slave device may have restrictions that lower the maximum quantity. The coils are numbered from zero; (coil number 1 = zero, coil number 2 = one, coil number 3 = two, etc.). The following table is a sample read output status request to read coils 0020 to 0056 from slave device number 11.
PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference The following table is a sample read input status request to read inputs 10197 to 10218 from slave number 11.

Reference PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Response The addressed slave responds with its address and the function code, followed by the information field. The information field contains 1 byte describing the quantity of data bytes to be returned. The contents of the registers requested (DATA) are two bytes each, with the binary content right justified within each pair of characters. The first byte includes the high order bits and the second, the low order bits.

Any coil that exists within the controller can be forced to either state (ON or OFF). However, because the controller is actively scanning, unless the coils are disabled, the controller can also alter the state of the coil.

PTQ-MCM ♦ Quantum / Unity Platform Modbus Communication Module Reference In this example, the client addresses a request to server device. The function code (01) is for a Read Output Status operation. It requests the status of the output at address 1245 (04A1 hex). Note that only that one output is to be read, as specified by the number of outputs field (0001). If the output address is non-existent in the server device, the server will return the exception response with the exception code shown (02).

The server (or slave) attempted to read record file, but detected a parity error in the memory. The client (or master) can retry the request, but service may be required on the server (or slave) device.
