Appendix F MicroLogix 1400 Distributed Network Protocol (DNP3)
These control codes and point models are implemented in the MicroLogix 1400
controller:
• 0x00 (NUL/NUL): Clear field Off
• 0x20 (NUL/NUL): Clear field On
• 0x01 (Pulse On/NUL): Clear field Off, Activation Model
• 0x21 (Pulse On/NUL): Clear field On, Activation Model
• 0x03 (Latch On/NUL): Clear field Off, Complementary latch model
• 0x23 (Latch On/NUL): Clear field On, Complementary latch model
• 0x04 (Latch Off/NUL): Clear field Off, Complementary latch model
• 0x24 (Latch Off/NUL): Clear field On, Complementary latch model
• 0x41 (Pulse On/Close): Clear field Off, Complementary two-output
model
• 0x61 (Pulse On/Close): Clear field On, Complementary two-output
model
• 0x81 (Pulse On/Trip): Clear field Off, Complementary two-output model
• 0xA1 (Pulse On/Trip): Clear field On, Complementary two-output
model
When the MicroLogix 1400 is in Non-Executing mode, the controller will not
accept a Binary Command. The MicroLogix 1400 returns a Control Status Code
7 in response. To access objects 12(CROB), the controller should be in Executing
mode.
Note that Executing mode includes Run, Remote Run, Test Continuous Scan,
and Test Single Scan modes. Any others are Non-Executing modes.
DNP3 Double Bit Binary Input Object
The supported object group and variations are listed in this section. The
MicroLogix 1400 responds with the default group and variation when the DNP3
Master requests to read an object with Any variation.
Double-bit Binary Input Static Objects:
• g3v0 - Double-bit Binary Input - All Variations
• g3v1 - Double-bit Binary Input - Packed format (default)
• g3v2 - Double-bit Binary Input - With flags
Double-bit Binary Input Event Objects:
• g4v0 - Double-bit Binary Input Event - All Variations
• g4v1 - Double-bit Binary Input Event - Without time
• g4v2 - Double-bit Binary Input Event - With absolute time
• g4v3 - Double-bit Binary Input Event - With relative time (default)
