Command Points Addressing
Command points must be configured in a database area that is updated in the
module. You must associate each point to a database address in the PTQ-104S
module. The interpretation of the DB address parameter in the configuration
tables depends on the point type configured and the type of addressing
associated with that point type.
Data Type Data Size Addressing Type
C_SC_NA 1 bit Bit
C_DC_NA 2 bits Bit
C_RC_NA 1 byte Byte
C_BO_NA 2 words Double-word
C_SE_NA 1 word Word
C_SE_NB 1 word Word
C_SE_NC 2 words Double-word
C_SC_NA and C_DC_NA

addressing. For example, if you configure the following points:
These points would be used as follows:
Inf. Object Address Module Database Address
100 Bit 0 of word 100
101 Bit 1 of word 100
102 Bit 2 of word 100
