5.4 Expansion module MAC00-B42
• Multifunction I/O 1 and 2 (A1± ,B1± , A2± and B2±)
(internal signals not supported externally)
• Digital inputs (IN1, IN2, IN3, IN4, IN5, IN6, IO7, IO8, and IO-)
The inputs can be read from the serial interface (RS232 or RS485) or they can be op-
erated from the user program stored in the motor.
The source that feed the inputs must be a PNP/source type.
The IO- terminal serves also as ground (common) for the user outputs.
• Digital inputs (O1, O2, O3, O4, and IO-)
The outputs can be set from the serial interface (RS232 or RS485) or they can be op-
erated from the user program stored in the motor.
The IO- terminal serves also as ground (common) for the user inputs.
• RS485 Interface (A-, B+ and GND)
Serial balanced interface for connection to a PC or a controller. The protocol is sim-
ilar to the RS232 or USB interface, which means that all registers/parameters in the
motor can be monitored or changed. The RS485 is recommended for longer distanc
-
es or in noisy environments.
• RS232 Interface (Rx, Tx and GND)
Serial unbalanced interface for connection to a PC or a controller. The protocol is
similar to the RS485 interface, which means that all registers/parameters in the mo
-
tor can be monitored or changed. RS232 is not recommended for long distances.
The MAC motor uses “binary” communication protocol which makes it possible to ac-
cess all the internal registers. Please consult MacTalk communication, page 402 for further
details.
5.4.4 Building ePLC programs
The MAC00-B42 module is primarily intended to be used as an I/O module which is
equivalent to the MAC00-R4 module but with upgraded features.
The overall software interface and programming is similar to the R4 module.
Therefore the description of the commands and how to build an ePLC program can be
found on the pages
MAC00-RxP Main window, page 315 and How to build a program, page
317.
