SEL-2020 Instruction Manual
Table 6.4: SET P Port Communications Settings Information (continued)
Setting Comment
ADDRESS
Prompt. First LMD Port Address (1 through 81).
Description. You supply a port address only if you selected LMD as the PROTOCOL.
The LMD address is the first of seventeen used by the SEL-2020; the defined address is for
SEL-2020 communications and the next 16 are for transparent communications to the
respective ports. (See Appendix C: LMD Protocol for an explanation of LMD protocol.)
PREFIX
Prompt. LMD Address Prefix Character (@#$%&).
Description. You supply LMD prefix character only if LMD was selected as the
PROTOCOL. The prefix setting is the character the SEL-2020 watches for when using
LMD protocol. (See Appendix C: LMD Protocol for an explanation of LMD protocol.)
SETTLE
Prompt. LMD Port Settle Time (0-30 seconds).
Description. You supply a LMD port settle time only if LMD was selected as the
PROTOCOL. (See Appendix C: LMD Protocol for an explanation of LMD protocol.)
MAP_TYPE
Prompt. Modbus Map Type (F=Float, I=Integer).
Description. Selection for Modbus map style. See Appendix G: Modbus Protocol for an
explanation of the two map styles.
START_ID
Prompt. Starting Code for ID List (0-255).
Description. Used to offset Modbus device ID list. (See Appendix G: Modbus Protocol
for reference information on Modbus.
SETTLE1
Prompt. Transmission delay from RTS assertion (0-30000 ms).
Description. Delay between RTS assertion and start of transmission. (See Appendix G:
Modbus Protocol for reference information on Modbus. See Appendix I: Distributed
Network Protocol (DNP) V3.00 for an explanation of the DNP protocol.)
SETTLE2
Prompt. Posttransmit RTS deassertion delay (0-30000 ms).
Description. Delay between end of transmission and RTS deassertion. (See Appendix G:
Modbus Protocol for reference information on Modbus. See Appendix I: Distributed
Network Protocol (DNP) V3.00 for an explanation of the DNP protocol.)
ADDRESS1
Prompt. Address of Port 1 (1-247).
Description. Modbus device address 1-247, or OFF if no Modbus access desired.
Similarly for ADDRESS2-16. (See Appendix G: Modbus Protocol for reference
information on Modbus.)
ADDRESS
Prompt. DNP Address (0-65534 or 0000h-FFFEh).
Description. Address of the SEL-2020. It must be unique from all other DNP addresses
on the connection. (See Appendix I: Distributed Network Protocol (DNP) V3.00 for an
explanation of the DNP protocol.)
CLASS
Prompt. Class for event data (0 for no event data, 1, 2, 3).
Description. Enter the DNP class, 1-3, to reference SEL-2020 event data under. Enter 0 if
you do not want any event data. (See Appendix I: Distributed Network Protocol (DNP)
V3.00 for an explanation of the DNP protocol.)
16BIT
Prompt. Use 16 or 32-bit default variations for analog inputs (16/32).
Description. DNP analog input objects can use default variations 16 or 32-bits in size. Set
this to 16 or 32-bit, based on which default you prefer. Generally 32-bit is preferable,
because you get a better range, but if your master does not support 32-bit analog inputs,
you must use 16-bit. (See Appendix I: Distributed Network Protocol (DNP) V3.00 for an
explanation of the DNP protocol.)
