Frequently Asked Questions

Which controllers are compatible with the 5069-SERIAL module?
The 5069-SERIAL module is compatible with CompactLogix 5380, Compact GuardLogix 5380, and CompactLogix 5480 controllers for local or remote use. For remote use only, it also supports ControlLogix 5580 and GuardLogix 5580 controllers. The module is not compatible with the 5069-AEN2TR adapter. Logix Designer Version 31.00.00 or later is required for most controllers; CompactLogix 5480 models require Version 32.00.00 or Version 32.01.00 or later depending on the specific catalog number.
What serial protocols does the 5069-SERIAL module support?
The module supports Generic ASCII, Modbus RTU/ASCII (Master and Slave), DF1 (Point-to-Point, Master, Slave, and Radio Modem), and DH-485. DF1 and DH-485 protocols use Channel 1 only and require the module to be installed locally. DF1 and DH-485 are not supported in remote I/O configurations. DF1 and DH-485 support requires firmware revision 2.011 or later and Add-On Profile version 2.01.
How many connections does the 5069-SERIAL module make to the owner-controller?
The number of connections depends on how both channels are configured. For example, if Channel 0 is Generic ASCII and Channel 1 is Modbus Slave, two connections are made. If Channel 0 is Generic ASCII and Channel 1 is Modbus Master, three connections are made. When both channels use Modbus Master, up to four connections are possible. A full connection table for all protocol combinations is provided in Table 3 of the manual.
Can the 5069-SERIAL module be used as a remote I/O module?
Yes. When installed in a separate location from the controller, the module operates as a remote I/O module accessible over an EtherNet/IP network via a Compact 5000 EtherNet/IP adapter. When used remotely, you must use the AENTR adapter. DF1 and DH-485 modes are not supported in remote configurations.
What is the Requested Packet Interval (RPI) range for the serial module?
The RPI range varies by protocol. Generic ASCII, DF1 variants, and DH-485 support an RPI of 2 ms to 750 ms in 0.1 ms increments. Modbus Master and Modbus Slave support 6 ms to 750 ms in 0.1 ms increments. If the RPI value is not a multiple of 0.1 ms, it should be rounded down to the nearest 0.1 ms multiple.
What is module inhibiting and when would it be used?
Module inhibiting lets you indefinitely suspend a connection between the owner-controller and the serial module without removing it from the configuration. It can be used to temporarily disable a module for maintenance, to update module firmware, or to configure a module in a project before the physical hardware is available. Once the module is uninhibited, the owner-controller re-establishes the connection and resumes normal operation.
What Modbus function codes does the module support when configured as a Modbus Slave?
When configured as a Modbus Slave, the 5069-SERIAL supports function codes 0x01 (Read Coil), 0x02 (Read Discrete Inputs), 0x03 (Read Holding Registers), 0x04 (Read Input Register), 0x05 (Write Single Coil), 0x06 (Write Single Register), 0x0F (Write Multiple Coil), 0x10 (Write Multiple Registers), 0x16 (Mask Write Register), and 0x17 (Read/Write Multiple Registers).
