Multiplexed analog Read Input Table
Registers 0300H to 037FH BCD-VALUES
Resisters 0400H to 047FH BINARY-VALUES
Multiplexed analog values only valid if Multiplexer is selected
Reading of 1 to 32 registers possible
Dupline group AB holds the actual Mux-address on the 4 most significant bits.
The remaining bits holds the digital transmit information from channel A5..B8
Active Devices found in the RS485 Network
32 bits indicating the presence of slaves in the Network
Register 2002h, MSB = Slave no 00 (central=0). LSB = Slave no 15
Register 2003h, MSB = Slave no 16 LSB = Slave no31.
2 Registers.
Reads information previously written by a Modbus command for transmission on
Dupline
Reading of 1 to 8 registers possible.
If an attempt is made to read from a start-address and the number of registers exceeds
the allowed register range, no answer will be made, as this is interpreted as an illegal
function
Reads information previously written by a Modbus command for forced output on
Dupline.
Reading of 1 to 8 registers possible.
If an attempt is made to read from a start-address and the number of registers exceeds
the allowed register range, no answer will be made, as this is interpreted as an illegal
function
Multiplexed Analog Read Output Table
Registers 1300H to 137FH BCD-VALUES
Resisters 1400H to 147FH BINARY-VALUES
Multiplexed analog values only valid if Multiplexer is selected
Reading of 1 to 32 registers possible
In the Binary Data-area, the transmitted data are checked against valid BCD coding and also the control-
its from the Analog transmitter.
Reading an “FFFF” indicates an invalid value or a non-existing analog transmitter.
Eg. Reading BCD data on Group C, then the channels C1 and C2 has to be active, before a binary value
are read. This is done automatically by the analog transmitters.
Active Devices found in Radio-Modem Network.
(When configured as Radio-modem Central)
32 bits indicating the presence of a Radio-Modem sbustation.
Register 2000h, MSB = Substation no 00 (central=0). LSB = Substation no 15
Register 2001h, MSB = Substation no 16 LSB = Substation no31.
2 Registers.
Read Generators internal 24 Hour clock.
Format: hh.mm, ss,dd,MM,DD,YYYY
Day of week: 1 Monday ..7 Sunday.
The Data format is BCD
ote: All 4 Registers must be read simultaneously.
