4-2-7 Data Allocations for Bit Slave Units
Bit Slave Units are allocated data in units of two bits (two points).
For example, eight Slave Units with two points each would be allocated one word. Likewise, four Slave
Units with two points each and two Slave Units with four points each would be allocated one word.
A Slave Unit with two points is allocated two bits in the node address area for the node address set for
the Unit.
A Slave Unit with four points is allocated four bits, two bits in the node address area for the node
address set for the Unit and two bits in the next node address area.
• Two-point Input Slave Units
• Four-point Input Slave Units
• Two-point Output Slave Units
• Four-point Output Slave Units
• Two-point I/O Slave Units
* The upper bits for two-bit I/O Units (marked "not used") are not used. The status of unused bits is as follows:
• Unused remote output (RY) bits: Do not turn ON these bits.
• Unused remote input (RX) bits: These bits will be OFF.
• Four-point I/O Slave Units
For Bit Slave Units, node address areas are used consecutively without spaces.
For example, one word would be allocated for eight Slave Units with two points each. Likewise, four
Slave Units with two points each and two Slave Units with four points each would be allocated one
word.
