Chapter 2 Devices Error codes for Ethernet connections 2_ The list of SM/SR states when connecting to RTU-EN01 throught Ethernet port Note: Before the connection is established, it is suggested NOT to use data (RX/RY/RCR Read/RCR Write) in the mapping area. 21. When selecting “Manual + Flags” in “I/O allocation setting when Power On”, use flags SM230-SM261 to activate the 1 st – 32 nd module on the right-side of the CPU module. (available for FW V1.06.00 or later ) For less module applications, you can use the same PLC program and download the I/O allocation table once for various I/O applications. Two things to be noted when applying this mode: A.
You need to use a bigger I/O allocation planning beforehand and store this planning in AS series PLC. B. You can simply use special flags to mark which I/O module will NOT be used to meet the actual I/O module placement. But you cannot rearrange the original order of the module placement. Add a new selection “Manual + Flags” for the setting option “I/O module allocation setting when Power ON”. Select this option, you need to use it with flags SM230-SM261. For less module applications, you can simply use special flags to mark which I/O module will NOT be used to meet the actual I/O module placement.
In this mode, you can use the same PLC program and download the I/O allocation table once for various I/O applications.
