  • Page 35: Addressing Overview

    Addressing Overview Addressing Overview All the memory used for external I/O processing and internal data processing has always both address and data (the content). Addressing space is classified as R, L, M, K, F , TC, and W. These letters are used to designate a specific area in memory as shown in the following table.

  • Page 36: Bit And Word Addressing

    The R, L, M, K, F , and TC areas can be used for both bit and word addressing. The W area can be used to process word data only. The L area can be used as internal contacts. Keep contact (K), data register (W), and counter's preset value register retain their last values before power was removed.

  • Page 105: Appendix. Communication Protocols

    Appendix Communication Protocols The communication protocol of NX-CPU700p PLC provides a complete method of communications between the graphic consol programmers (WinGPC) and the PLC by controlling programs, CPU status, and I/O at user’s convenience. The user can easily expand the capabilities of the overall PLC system by communicating to the PLC using a variety of peripheral communications equipment in accordance with the following communication protocols and procedures.

  • Page 106: Communication Protocols

    Communication Protocols Step 1-Q Query Query Q (Query) is a signal sent from the peripheral devices to the PLC after setting the network ID number and the function code for the PLC to communicate with. Step 2-QA Query Acknowledge Query QA (Query Acknowledge) is a signal sent from the PLC to the peripheral devices, indicating that the Q signal from the peripheral device was received.
  • Page 107 When several CPU modules are connected to one communication network, they must use individual ID numbers. The PLC’s network ID number is configured using the WinGPC. Communication steps The NX CPU can support 2-step or 4-step communication methods. The communication methods are easily distinguished each other by selecting and sending the function code of the Q frame.
  • Page 108 2-step communication method No communication error Peripheral device When R is not received 3 seconds Peripheral device Response to repeated function code Peripheral device 4-step communication method No communication error For the internal processing of the PLC CPU send RR at least 5 msec after receiving QA.
  • Page 109 Function codes included in the query Each function code is 1 byte. When the PLC receives a query (Q), the function code of the final response (R) is formed by adding $80 (hex) to the function code sent by the query. The value added to the function code sent by the query differs for 2-step and 4-step by $20 (hex).
  • Page 110 Cyclic Redundancy Checking (CRC) The CRC is a 2-byte checksum code attached to the end of the message by the sender to check if the communication frame is transmitted without error. The sender calculates the CRC when it sends one-byte message, and the receiver should also calculate the CRC from the data of the message.
