(2) Data Command Transfer (Control Bits: Read (H'3, H'7), Write (H'A, H'B, H'E, H'F))
In the case of data read (H'3, H'7), data in the data buffer of the slave unit is read in the master
unit. In the case of data write (H'B or H'F) or command write (H'A or H'E), data received in the
slave unit is processed in accordance with the operation specification of the slave unit.
Notes: 1. The user can select data and commands freely in accordance with the system.
(3) Locked Address Read (Control Bits: H'4, H'5)
In the case of the locked address read (H'4 or H'5), the address (12 bits) of the master unit which
issues lock instruction is configured in bytes shown in figure 14.4.
(4) Locking/Unlocking (Control Bits: Setting (H'3, H'A, H'B), Cancellation: (H'6))
The lock function is used for message transfer over multiple communications frames. Locked unit
receives data only from the unit which has locked.
Locking and unlocking are described below.
• Locking
• Unlocking
When the acknowledge bit of 0 in the message length field is transmitted/received with the
control bits indicating the lock operation, and then the communications frame is completed
before completion of data transmission/reception for the number of bytes specified by the
message length bits, the slave unit is locked by the master unit. In this case, the bit (bit 2)
relevant to lock in the byte data indicating the slave status is set to 1.
Lock is set only when the number of data exceeds the maximum number of transfer bytes in
one frame. Lock is not set by other error termination.
When the control bits indicate the lock (H'3, H'A, or H'B) or unlock (H'6) operation and the
byte data for the number of bytes specified by the message length bits are transmitted/received
2.
H'3, H'A, or H'B may lock depending on the communications condition and status.
