TRANSMISSION DATA DESCRIPTIONS
■ MEASURANDS
• 16-word Mode (standard)
Measurands and assigned word numbers are specified using the R3CON PC Configurator.
Max. 16 words per module (slot). 1 word = 16 bits, 2 words
= 32 bits
• 32-word Mode (option /D)
Measurands and assigned word numbers are specified using the R3CON PC Configurator.
Max. 32 words by virtually assigning addresses (n) and (n+1) per module. 1 word = 16 bits, 2 words = 32 bits
Be sure to use the R3-BSW base with free address setting capability. DO NOT assign the address (n+1) to any module.
A duplicate address will cause malfunctions.
■ RESET
Measurands to be reset can be specified among: all energy values, MAX / MIN current values, MAX / MIN values other than current and AVG (demand) values.
Refer to ‘I/O DATA DESCRIPTIONS’ in the R3-WTU instruction manual for resetting from the host device.
For detailed information for the selection of measurands and other settings, refer to the R3CON Users Manual.
