Introduction

An M580 system can include software configuration, services, and features that you may already use in your existing system.

Control Expert Software

Control Expert software is used in an M580 system.

For detailed Control Expert configuration procedures, refer to the respective Modicon M580 [Module] Installation and Configuration Guide.

CCOTF Function

The Change Configuration on the Fly (CCOTF) function allows I/O configuration changes in the Ethernet RIO drops when the CPU is in STOP or RUN mode.

Detailed information is available in the Modicon M580 Change Configuration on the Fly User Guide.

Time Stamping

  • For Modicon X80 RIO drops on an X Bus backplane, time stamping is managed by a BMX ERT 1604 module installed on the RIO drop with a resolution of 1 ms. The BMXCRA31210 X80 performance EIO adapter module also manages this functionality.

  • For Modicon X80 RIO drops on an Ethernet backplane, time stamping is managed by a BMECRA31210 X80 performance EIO adapter module installed on the RIO drop with a resolution of 10 ms.

  • Inputs or outputs of X80 digital modules can be time stamped in an RIO drop with a BM• CRA 312 10 X80 EIO adapter module..

  • Local variables can be time stamped in the PAC.

The BMXCRA31210 and BMECRA31210 eX80 EIO adapter modules have the same resolution/accuracy for a given NTP server. The accuracy is better if a dedicated NTP server is used instead of an M580 CPU as the NTP server.

Ethernet Services

As mentioned previously, some CPUs support both RIO and DIO scanning services, and others support only DIO services. The Ethernet services that can be used on these classes of M580 CPU differ as follows:

NOTE: Enable Ethernet (ETH) and backplane ports and select their respective baud rates.

M580 modules communicate using these parameters, which can be configured with Unity Pro 10.0 or later.

  • IP address (See the configuration topic in the respective Modicon M580 [Module] Installation and Configuration Guide.)

    NOTE: The BM•CRA312•0 EIO adapter modules automatically receive an IP address. You cannot change this IP address on this screen. Open the Control Expert CPU configuration screen to change the IP address.

  • RSTP (See the configuration topic in the respective Modicon M580 [Module] Installation and Configuration Guide.)

  • SNMP (See the configuration topic in the respective Modicon M580 [Module] Installation and Configuration Guide.)

  • service port (See the configuration topic in the respective Modicon M580 [Module] Installation and Configuration Guide.)

  • SNTP (See the configuration topic in the respective Modicon M580 [Module] Installation and Configuration User Guide.)

Explicit Messaging

M580 CPUs and Ethernet communication modules support explicit messaging via EtherNet/IP and Modbus TCP protocols. This feature is detailed in the respective Modicon M580 [Module] Installation and Configuration Guide.

Use explicit messaging for extended diagnostics. These are the methods for explicit messaging in M580 systems:

  • EtherNet/IP or Modbus TCP explicit messaging using one of the following function blocks:

    • READ_VAR

    • WRITE_VAR

    • DATA_EXCH

  • explicit messaging via the Control Expert graphic user interface, as described in manuals such as the M580 Hardware Reference Guide and the BME NOC 03•1 Ethernet Communications Module Installation and Configuration Guide.

NOTE: For detailed information regarding these function blocks, refer to the Extended part in the Unity Pro Communication Block Library user manual.
