Subfunction Code: 2A hex

This datagram is used to read the Series 90±70 I/O references assigned to a Remote

I/OScanner, and its Remote Drop ID.

Data Field Format: none

Read Map Reply

Subfunction Code: 2B hex

A Remote I/O Scanner sends this reply datagram after receiving a Read Map datagram. It contains the Series 90±70 I/O references assigned to the Remote I/O Scanner, and its Remote Drop ID. It provides no information about the I/O assignments of individual I/O modules in the remote drop. However, the checksum supplied indicates that the overall configuration remains unchanged.

Byte No.

The Remote Drop ID is a unique number between 16 and 254 that identifies the remote drop.

Starting references in %I, %AI, %Q, and %AQ memory may be returned. For each memory type, a data length is also supplied. If zero, the associated starting reference can be ignored; it is not meaningful.

Subfunction Code: 2C hex

This datagram allows a CPU to send Series 90±70 I/O addresses and a Remote Drop ID to a Remote I/O Scanner. If the Remote I/O Scanner receives this message, and its configuration is not currently protected (by means of the Hand±held Monitor's Con- figuration Protect feature), the I/O modules present in the remote drop are automati- cally configured. Data format for this datagram is the same as Read Map Reply.

The checksum must be included in the message, even though its values are ignored.
