Table 6.2 Example 1: Displaying a complete display line
STX 1F Line Cursor Position Character 1 ... Character n ETX
Table 6.3 Example 1: Displaying a complete display line
STX 1F Line Cursor Position Character 1 Line Cursor Position Character 2 ... ETX
If another (STX) character is sent before an output data stream ended, the complete display is cleared (e.g. in case
of sporadic interruption of communication), and the transmission is restarted.
■
Drive Controller Remote Keypad Control (1F (Hex))
In this mode, the keypad of the lift controller is used to pass user input to the drive controller. Switching to this
mode is initiated with the character string (STX) (1F (Hex)) and ends with an (ETX) character.
A keystroke transfer has the following format:
STX 1F (Hex) Button ETX
■
Idle State
If data is not being communicated on the channel, null bytes are transferred (0 (Hex)), i.e. communication is
idling.
0 (Hex)
■
Synchronization / Communication Device Reset
The communication device can be reset to its initial state (display cleared) at any time with the character string
(STX) (ETX) (generally recommended before switching control mode 1C, 1E, 1F (Hex)).
STX ETX
In the initial state, all Tx and Rx communication buffers of the drive are cleared. The drive is ready to receive any
new valid message from the lift controller.
■
Saving Device Controller Error Messages (1E (Hex))
It is possible for the drive controller to intervene asynchronously in an exchange of messages at any time in order
to display drive controller error messages on the lift controller display and to save it to the lift controller's event
log.
If a message transmission is already in progress, the drive controller first completes this message before sending
the error message. Following this procedure prevents a loss of data. Switching to this mode is initiated with the
character string (STX) (1E (Hex)) and ends with an (ETX) character.
An error message output has the following format:
STX 1E (Hex) Character 1 Character 2 ... Character n ETX
n = 1 to 20
The Error message for Yaskawa drives is specified as follows: Only the LCD Message Fault Display is
transferred, e.g. "EF3" for External Fault 3, not the fault Message text "Ext Fault S3". The same fault is
transmitted only once and is not repeated unless another fault has occurred in the meantime.
■
Extended Data Communication between Lift and Drive Controller (1C (Hex))
In this mode, additional data can be exchanged between lift controller and drive controller. Switching to this mode
is initiated with the character string (STX) (1C (Hex)) and ends with an (ETX) character.
Extended Data Transmission in Communication Channel (1C (Hex))
The messages defined by the date of publication of this document are described below. The lift controller always
initiates communication. Only the drive controller responds.
Initialization Message ('I' '0')
The lift controller and the drive controller start communication with the following initialization messages. After
that, both of the controllers check and adjust their settings.
The drive controller receives the language settings from the lift controller and switches to the same language.
When the drive controller is not able to support the received language setting, it needs to switch to English
language (same as default setting).
