Operation Manual, Eighth Edition

Table of Contents

1. Overview

The open field network ProfiBus-DP is a multi-bit, multi-vendor network for communication of both control and

data signals of the machine/line control level.

A wire-saving system can be built by connecting IAI’s X-SEL, TT, RCS-C, E-Con, ACON, PCON, SCON, ASEL,

PSEL and SSEL controllers (hereinafter collectively and individually referred to as “Each Controller”) to a

ProfiBus-DP network.

Each controller is treated as a slave station in ProfiBus-DP and can be used to exchange I/O data.

* For details on ProfiBus-DP, refer to the operation manual for the programmable controller (hereinafter referred

to as “PLC”) in which the master unit is installed.

This operation manual should be used in conjunction with the operation manual for each controller.

You should also assume that any usage not specifically permitted in this operation manual is prohibited.

*1 The baud rate of a ProfiBus-DP network can be specified only when the ProfiBus-DP network is set up using

a configurator (*2).

The baud rate of all ProfiBus-DP slave modules is set with this configurator, and therefore a different baud rate

cannot be set for an individual slave station.

*2 For the ProfiBus-DP configurator, use the configurator recommended for the master unit.

3. X-SEL Controller

3.1 ProfiBus-DP Board Types and Installation Positions in the X-SEL

There are six types of X-SEL controllers that support ProfiBus-DP, as listed below. The installation position of the

ProfiBus-DP board is different depending on whether the X-SEL controller is of PR0 type or PR1 type.

* The PR1 board can be installed in any one of expansion I/O slots 1 to 3.

*2 The ProfiBus-DP board is installed in the same position as shown in Fig. 3.4. With a 5-axis or 6-axis

specification, the ProfiBus-DP board is installed in the same position as with a 4-axis specification.

Fig. 3.1

*1) An I/O board cannot be installed in 1-axis and 2-axis specifications, because the ProfiBus-DP board

occupies the only slot available.

*2) With 3-axis and 4-axis specifications, only the “PR0” ProfiBus-DP board can be installed in the standard slot.

*3) With 3-axis and 4-axis specifications, one expansion I/O board can be installed in the expansion slot.

(2) General-purpose type (K type)

zEither a ProfiBus-DP board or standard I/O board must be always installed in the standard slot (I/O1 --- slot

at the far left).

zThe “PR1” ProfiBus-DP board occupies two expansion slots. If this type of ProfiBus-DP board is selected,

only one expansion slot can be used.

zEither an expansion I/O board*1 or SIO board*2 can be installed in an expansion slot.

(Note) [5] and [6] are used exclusively for the K, P and Q types, while [7] and [8] are used

exclusively for the J type.

For specification details, refer to “Operation Manual for X-SEL Controller.”
