No official successor order code exists for this unit. If your CS1 rack still needs this conversion block, sourcing through an independent distributor who can pull from multiple surplus inventories is the realistic path. For a line-down situation, confirm the exact CPU model and slot position — the conversion block's terminal assignment must match the I/O module it serves.","metaTitle":"Omron CS1W-AT211 I/O Terminal Block Conversion Unit","metaDescription":"Omron CS1W-AT211 I/O terminal block conversion unit for CS1-series PLCs.
