YASKAWA MP2000 series machine controller communication module

YASKAWA MP2000 series machine controller communication module

The entire process of starting the communication module

Step 1: Prepare using the machine

Essential equipment: MP2000 series controller, communication module, communication partner device, dedicated cable, computer with MPE720 installed

Controller compatibility: MP2200 (JEPMC-BU2200/BU2210, maximum of 8 modules), MP2300 (JEPMC-MP2300, maximum of 3 modules), MP210M (JAPMC-MC2140, expansion board required, maximum of 8 modules), MP2500MD (JEPMC-MP2540-D , expansion board required, maximum of 8 modules)

Step 2: Module installation and disassembly

Installation steps: Power off → Remove the machine controller battery cover → Remove the optional module cover → Align the guide rail and insert the module → Install the cover → Power on

Disassembly steps: Power off → Backup program → Remove cable → Remove battery cover → Remove cover → Use battery cover protrusion to pry module → Pull out module

Step 3: Communication Manager Settings

Supported port types: Serial (RS-232C), Ethernet, Ethernet (LP), CP-215

Key setting example (Ethernet): Set the computer IP to 192.168.1.2 and subnet mask to 255.255.255.0; Set the Logical PT to Ethernet and fill in the computer IP address for the Communication Manager

Step 4: Automatic Configuration Execution

Trigger method: Set "CNFG" to ON and restart MP2200/MP2300; MP210M/MP2500MD operated through the MPE720 menu

Result difference:

CNFG Initiate Results

The ON module has been updated, and all communication modules are configured according to default settings

The ON/OFF module has been updated, with existing modules retaining their configuration and new modules using default settings

Step 5: MPE720 Startup and Transfer Definition

Ver.6: Online → Communications Setting → Select Logical Port → Set Parameters

Ver.5.xx: Start MPE720 → Open PLC folder → Properties → Network → Check OnLine → Select logical port

Transfer definition: Open the module composition definition screen → double-click the corresponding module → set parameters → save to flash memory

Detailed explanation of transmission mode and protocol

Classification of transmission modes

Mode applicable communication mode (module) core characteristics

Information transmission RS-232C (all), Ethernet (218IF-01/02), MPLINK (215AIF-01) event triggered, using MSG-SND/MSG-RCV functions

Engineering transmission RS-232C (all), Ethernet (218IF-01/02), MPLINK (215AIF-01) panel commands+MPE720 for program transmission

Link Transport MPLINK (215AIF-01) regularly sends and receives, only supported by 215AIF-01

Core Communication Protocol

MEMOBU: Yaskawa standard, main controller specifies sub controller address communication, function codes include 01H (read winding), 03H (read hold register), etc., supporting 1-2000 bits (bit data), 1-125 words (word data)

Extended MEMOBU: MEMOBU extension, adding function codes such as 09H (extended read hold register), transmitting 1-508 words at once, supporting MEMOBU/general information mode

MELSEC: Compatible with Mitsubishi A-series, supports communication between CPUs and fixed buffer communication, with function codes corresponding to ACPU universal commands (such as WR → 01H/02H)

MODBUS/TCP: Industrial Ethernet protocol, supports 1-2000 bits (read winding), 1-125 words (read register), 218IF-01/02 automatic conversion protocol

No steps: Directly transfer data from the M register, divided into word (1-254 words) and byte (1-508 bytes) units, with no response

Serial communication (taking 217IF-01 as an example)

Ports and protocols

Interface: RS-232C (PORT, 9-pin), RS-422/485 (14 pin)

Supporting protocols: MEMOBU, MELSEC, OMRON, Stepless, Stepless FD (Full Duplex, Maximum Received 5080 Words)
