  • Page 108 Communications Mode CP 523 7.1.1 3964 and 3964R Protocols (relevant in 3964(R) mode only) Protocol data The 3964 and 3964R protocols control the flow of data between your programmable controller and the partner in the communications link. The data to be transmitted must be entered in the CP 523's output buffer, and is then forwarded to the partner in the link together with the 3964 or 3964R protocol.
  • Page 109 CP 523 Communications Mode If the connection can be established, the useful data in the output buffer is transmitted to the partner in the link at the specified baud rate. The partner in the link monitors the interval between incoming characters, which may not exceed the character delay time (ZVZ)*. Each DLE character found in the buffer is transmitted as two DLE characters (double DLE), i.e.
  • Page 110 Communications Mode CP 523 Receiving When no Send request is pending in 3964(R) mode, the CP waits for the link partner to establish a connection. If the CP receives a character (other than STX) while in the idle state, it waits until the character delay time has expired (ZVZ) and then sends NAK.
  • Page 111 CP 523 Communications Mode If transmission errors occur during reception (characters are lost, framing error, parity error), the CP continues receiving until the connection is cleared down, transmits NAK to the link partner, and waits for a retry as described above. Example of error-free data interchange: CP 523 Partner in the link...
  • Page 112 Communications Mode CP 523 Initiation conflict If one partner in the link replies to a line bid (STX character) from the other link partner with STX instead of DLE or NAK, the result is an initiation conflict, i.e. both link partners want to transmit. The low-priority partner retracts its line bid and sends DLE.
  • Page 113 CP 523 Communications Mode Protocol Errors The protocol can detect errors caused by incorrect behaviour on the part of the link partner and errors caused by disturbances or interference on the line. In both cases, an attempt is first made to transmit or receive the message frame without error by initiating a retry.

The additional return information pertaining to the itself is entered in a coordination byte (CBS, CBR).
  • Page 188 CP 523 Communications Mode Example: Receiving a 12-byte message frame with 3964(R) protocol Base address 128 is set on the CP. The message frame is to be stored in data block 21 beginning DW 0. Flag 101.0 is to be set as soon as a message frame is entered in data block 21. The statement list does not explain how or when flag 101.0 is reset.
